There is "All asteroids of catalog" option, allows for transits and actual aspects to consider all asteroids, contains in catalog of asteroids, or specified number of first asteroids of catalog, or any set of asteroids, listed in

"aselected.txt" file.

If press "All asteroids of catalog" button, then following panel opens:

Along with main "All asteroids of catalog" option there are:

· "Asteroid-asteroid aspects" option, if checked, then in the "actual aspects" mode considered all mutual of all asteroids of catalog,

· "First N asteroids" option, if checked, then considered a number of first asteroids of catalog, specified in a rightmost field,

· "Use list of selected asteroids" option, if checked, then considered only asteroids, listed in "aselected.txt" file, this file contains the asteroids names, one name by string,

· "OK" button used to close this panel.

The button at the sane time is the indicator of "All asteroids of catalog" option: if pressed (down), then the option is on, if unpressed (up), then off. You may open the "All asteroids of catalog" panel without pressing this button, but just click it by right mouse button.

Graphic Ephemeris

The Graphic Ephemeris in ZET is more than a visual ephemeris. With options to include radix planets and houses, and directed and progressed planets, and to fold the display by harmonic factors, it is a true astrologers tool for determining moments of astrological interest.

A Graphic Ephemeris is prepared by clicking the "Tools" Toolbar button or selecting "Tools" from the main menu, then selecting the "Graphic Ephemeris..." menu item.

After completing the settings described below, a window is displayed with a graphic similar to this:

The Graphic Ephemeris window can be resized as desired.

The time scale is at left. The wavy lines sweeping down the chart represent movements of the planets. Vertical green and gray lines (if present) indicate the positions of radix planets and house cusps.

The chart is color-banded intelligently depending on the selected mode of representation. For example, for actual movement of planets thru the Zodiac, the bands indicate the cycle of sign quadruplicity. If house cusps are included, banding is by house, as shown above - angular houses (1,4,7,10) are tinted light-blue, succedent houses (2,5,8,11) in yellow, and cadent houses (3,6,9,12) white. If a harmonic factor is selected, banding is done in a comparable way.

The screenshot above (created in Transit mode) makes it evident, for example, when and where planet ingresses into signs and houses take place; and when transiting planets conjoin natal planets.

To check other aspects, click and drag the mouse in the diagram to display the Aspect Measure tool. The Aspect Measure is graduated with astrological aspects from the current orb table, and automatically scales to the diagram size. By sliding the 'conjunction' index mark (at the pointer position) along a planet's path, it is possible to determine dates and times for aspects for further astrological investigation, e.g. by erecting the aspect's Dynamics Diagram.

Settings

Period - select from the drop-down listbox one of the pre-defined periods: 3 days, 1 month, 1 year, 10, 30, 60, 120 years. Input a start date for the ephemeris in the entryfields below the Period listbox.

Mode of diagram - select Transit, Progression, Direction, etc from the drop-down list. For a standard planetary ephermeris in graphic form, select "Transit", then proceed to selection of planets. When you select Progression or Direction, a drop-down listbox becomes available below the Mode listbox, which allows you to select the specific type of progression or direction.

Planet selection boxes - the lower box is always labeled 'Natal'. The upper box is labeled according to the Mode selected.

To select an object, left-click a glyph in a selection box of planets and houses. Click again to de-select the object. Selected objects are shown in black (by default) or colored - if the glyph is gray, the object is not selected. You can select any set of planets for both charts.

To color a planet for the diagram, right-click its glyph to display a Color picker dialog, and select a color. Planets in Houses - checkmark the box to include house cusps on the diagram. When the box is checked, the horizontal axis of the diagram is labeled with Zodiac signs and houses, and visual banding follows the sequence of houses.

Harmonic factor - select from the drop-down listbox one of: 360°, 90°, 60°, 45°, or 30°.

· Harmonic 360° creates a diagram with the Zodiac extending conventionally across it. Planets' positions are depicted in 0-360° of celestial longitude. This representation shows aspects of conjunction clearly - they occur at the times and zodiacal longitudes where lines of planet movement intersect. Other aspects are not so apparent, but...

194 | P a g e · Harmonic 90° produces a diagram with a horizontal axis of 0°... 90°, and in which planets' coordinates have been divided by 4, i.e. the Zodiac has been folded. With this type of representation, intersections of lines indicate aspects of conjunction and/or square and/or opposition. Similarly,

· Harmonic 45° folds planets' longitudes by a factor of 8. In addition to the properties of the harmonic 90° setting, line intersections on the diagram now also indicate the possible locations of semisquare and sesquiquadrate aspects,

· and so on.

Examples

This example shows how to create a Graphic Ephemeris of annual transits for a nativity: 1. Enter the nativity details into the Event Data window, and erect the native's chart, 2. Open the Graphic Ephemeris dialog. For Period, select "1 year",

3. Set the start month and year,

4. For the Mode option, select "Transit",

5. In the Transiting box, click to select all the planets except the Moon. (Since the Moon is fast-moving, selecting transits of the Moon for 1 year would generate too many aspects and block up the diagram), 6. In the Natal box, select all the planets,

7. In the Harmonic setting, select "360°",

8. Click the "Create" button. A blue progress-bar shows the state of computation. When it is finished, the graphic ephemeris is automatically displayed in a new window.

To create a standard ephemeris for the planets in graphic form: set the desired Period and the start date, and select "Mundane Aspects" mode. Select the planets from the Actual selection box. A Harmonic setting is optional.

Astronomical Data

The Astronomical Data window is opened by selecting "Tables" from main menu or by clicking the "Tables" Toolbar button, then selecting the "Astronomical Data" menu item.

The header panel contains the following general information for the current time:

· Julian date equivalent of the current event time and date (Universal Date and Time), · local sidereal time,

· Ephemeris amendment (dT),

· Sidereal Ayanamsa (SA) - the difference between tropical and sidereal zodiacs, if a sidereal zodiac has been selected,

· Average obliquity of the ecliptic (Eo) - the inclination of the Earth's rotational axis, which also determines the maximum value of declination of the ecliptic,

· Equatorial inclination of nutation (dE), · Equatorial longitude of nutation (dF).

The astronomical data for planets and other bodies is as follows (unless the display has been customized - see popup menu options below):

· Ecliptical geocentric longitude, · Ecliptical geocentric latitude, · Equatorial right ascension, · Declination,

· Hour angle, · Altitude,

· Horizontal azimuth (i.e. bearing),

196 | P a g e · Angular speed (ecliptical geocentric) in degrees per day,

· Maximum angular speed,

· Angular speed as a percentage of maximum,

· Angular diameter (apparent visible size) in arc-minutes, · Inclination of the planet orbit to the ecliptic (i)

· Eccentricity of orbit (eks),

· Semimajor axis of orbit in a.u. (A),

· Longitude of the Ascending Node of the orbit (O), · Perihelion of orbit (P),

· Ecliptical heliocentric longitude (l) · Ecliptical heliocentric latitude (b), · Radius-vector planet - Sun in a.u. (R),

· Rectangular ecliptical heliocentric coordinates in a.u. (X, Y, Z), · Longitude of the north pole of the orbit,

· Latitude of the north pole of the orbit.

Click the right mouse button in the table to display a popup menu with the following options:

· Decimal format - sets a decimal-fraction degree format for displaying the table data (rather than degrees, arc-minutes, arc-seconds where appropriate),

· Save As... - opens a file Save dialog, allowing you to save the table to a plain text file. The planet data section of the file consists of tab-separated items. The suggested folder and file name is

[ZET]\Wrk\Astro.txt,

· Copy Cell - copies the data of the cell under the mouse pointer when the menu was invoked to the Clipboard.

· Columns... - opens the Column Manager dialog. You can select which columns will be displayed by marking the checkboxes in the list of column headers. To rearrange the order of columns in the table, click the pair of buttons at right to move the highlighted item up or down the list.

Cosmos

The Cosmos tableau is displayed by selecting "Tableau" | "Cosmos" from the main menu, or by clicking the "Cosmos" Toolbar button.

The tableau presents a 3D view of the Solar system as it would be seen from a point in space. Planets, their orbits, and background stars are visible. The view is authentic - objects are drawn to scale and in their correct position for the select moment in time.

When the tableau is first displayed (or redisplayed), it uses the current event-data date and time. This is updated if you use Dynamics of Time or Location operations in the tableau. However, if you select Motion for the tableau (see section below), this will not affect the event-data.

Pausing the mouse pointer over any object in the tableau (planet, star, asteroid) displays its name or designation in a popup info tooltip.

To orient the observer, at top-right the tableau has an X/Y/Z-axis vector for the system of rectangular ecliptical coordinates used in the tableau. At top-left is displayed the distance in Astronomical Units (au) from the central object of the tableau to the observer, and the rectangular ecliptical coordinates of the observer relative to this object.

To reposition the viewpoint click in the tableau and drag the mouse with the button held down, or use the four arrow buttons at the right of the Toolbar (keep pressed for continuous rotation). Vertical X-axis movement rotates the angle of sight, horizontal Z-axis movement relocates the viewpoint around the system.

You can also use the cursor (arrow) keys on the keyboard: · press the arrow keys alone for smooth movement,

· press the Ctrl key together with the arrow keys for faster movement, · press the Alt key together with the arrow keys for fastest movement. · press the Shift key together with the arrow keys for very slow movement.

198 | P a g e To approach or withdraw from the central object, click the "Approach (Home)" bullet button or the "Recede (End)" point button on the Toolbar,

or use the Home and End keys. You can obtain faster movement by pressing Ctrl+Home and Ctrl+End, or Alt+Home and Alt+End. For very slow movement use the Shift+Home and Shift+End key combinations.

The Approach/Recede facility differs from the telescopic Zoom In/Out option. The former simulates smooth actual movement thru real space, the latter is the equivalent of stepping the zoom level in a telescopic view of the object. These functions differ in the type of perspective they create.

To operate the telescopic Zoom function click the "Zoom In (PgUp)" bullet and "Zoom Out (PgDn)" point buttons located on the Toolbar,

or use the "Page Up" and "Page Down" keys.

Sometimes extremely slow movements are needed (e.g. to view eclipses). In this case set the "Speed of Movement" divider to a different factor:

Pull down the red bar to reduce the speed by a factor of 10, 100 or 1000.

You can increase and decrease the imaged brightness of stars using the "Star Brightness" buttons:

The Cosmos tableau can be animated (see Dynamics of Time).

Right-click the mouse for a popup menu. (Some menu options may be unavailable, depending on the object under the mouse pointer). TIP: to ensure menu options are correctly enabled for the object, wait until the tooltip name or designation is displayed before clicking.

Jump

The Jump option transitions (teleports!) the observer within the system to the chosen planet or star. After jumping, the selected object will be at the center of the tableau.

If you teleport too far from the Sun, you can get lost among the stars. If that happens use the "Return to Sun" menu option.
