NGC 0507 in 61007000

Cluster Images Below are the summed, smoothed, and exposure corrected images for the GIS and SIS. The images were smoothed with a Gaussian of 1.5 pixels. The regions inside the solid green lines were extracted for the source spectrum. Red, dashed lines enclose regions excluded. RA: 20.89345 DEC: 33.25384 Rext: 9.00 arcmin

Detector Images Below are images of each detector showing the region file used for that instrument. The images are smoothed with a Gaussian of 1.5 pixels and are not exposure corrected. The regions inside the solid green circle were extracted for the source spectrum. Regions inside dashed red circles were excluded from the source and background detections. Note that the current version of XIMAGE does not correctly display the ellipse and polygon regions used to define non-detector regions and SIS chips.

Optical Image An overlay of GIS contours on optical Digitized Sky Survey images for the GIS source region (as indicated by the circle). This is not yet perfected so some of these images may look screwy.

The X-ray Spectrum The x-ray spectrum of the cluster for a single temperature MEKAL fit, the residuals of the fit, and the fit parameters. Note that the spectrum from 0.6 to 10 keV is shown for each instrument although a smaller range of energies was usually fitted (e.g., 0.8 to 8.0 keV for the GIS and 0.6 to 8.0 keV for the SIS). The data points (lines) in white, red, green, and blue represent the data for each instrument (or corresponding model) in the order they were read into XSPEC, usually G2, G3, S0, S1. nh20 Tx 90% c.l.
