Figure

Figure 1. Basic results from the survey. The top panel contains a composite image of the field, in which the counts have been divided by an exposure map to provide an estimate of the 0.5–8.0 keV flux
Figure 2. Three-color image of the survey area. Red is 1–3 keV, green is 3–5 keV, and blue is 5–8 keV
Figure 4. Distribution of measured hardness ratios, (h − s)/(h + s), where h and s are the numbers of counts in the higher and lower energy bands, respectively.
Figure 5. Summary of the properties of long-term variables. We plot the ratio of the maximum to minimum fluxes against the maximum flux
