Three-color image of xclass1365 extracted from the LS DR9. The yellow circles represent galaxies observed with MISTRAL, along with their redshifts. The blue circle indicates the source was also measured in the SDSS (with concordant redshift). North is up and east is left, and the field of view is 1.87′ wide. The white contours correspond to the X-ray contours smoothed and filtered with a wavelet algorithm.
