† Click the link to see the optical image with overlaid X-ray contours.
The X-ray contours are computed on XRT images in the 0.5-2 keV band with the Chandra Ciao software, and the contours are drawn at respectively 5, 9, 15, 25, 50, 90, 150 and 300 sigma, where sigma is given by the local background level.
For all sources imaged by the Sloan Digital Sky Survey (SDSS), we use r-band SDSS images, and the image size is 3x3 arcminute, unless the SXCS source fall near the border of the SDSS. In this case, the size of the image is accordingly smaller. For all the SXCS sources that are not imaged by the SDSS, we make use of the SAO Digitized Sky Survey Server (DSS) optical images. Image size is always 3x3 arcminute.
