Fig. 24


Aitoff projection in Galactic coordinates of the sky distribution of 2RXS sources with HR1 errors smaller than 0.5. The size of the data points scales with the source count rate, and the colour represents the HR1 value. Sources in the hardness ratio intervals HR1 = [−1.0,−0.5] are indicated in red, HR1 = [−0.5,0.0] in magenta, HR1 = [0.0, + 0.5] in green, and HR1 = [ + 0.5, + 1.0] in blue.
