Magnitude comparison with Griffith et al. (2012). Step histogram in gray (dot-dashed line) show common sample, while step histogram (continuous line) show remaining OTELO sources with no matched counterpart from ACS-GC (i.e. only found in OTELO). Filled gray and black histograms correspond to the morphological sample (see Sect. 4.2) from common sample and without counterpart from ACS-GC (i.e. only found in OTELO), respectively. Numbers in the legend indicate the number of sources in the particular sub-sample.
