RGB map of the Virgo Cluster out to three times the virial radius of the cluster (red for 0.3 − 0.6 keV, green for 0.6 − 1.0 keV, and blue for 1.0 − 2.3 keV) is shown. The surface brightness for all channels has a dynamic range from 10−5 to 1.8 × 10−3 counts/sec/arcmin2. The map was rescaled by a factor of 5 in each dimension, but no smoothing was applied.
