Redshift distribution of the J1030 Chandra catalog. The histograms show the distribution for the whole sample (blue dashed) and the distribution for the objects with spectroscopic redshift (red filled). A spectroscopic redshift is available for 135 out of 243 objects. Also shown is the redshift lower limit for the 20 objects for which the photometric redshift probability distribution is flat (green striped).
