      Description

      Here is the feedback from the redshift measurements on the faint galaxies of the November run, after comparison with the reference redshifts. As I have identified issues that look independent from each other to me I will create other tickets attached to this one. 

      The horizontal lines in the "measured z" vs "reference z" plot denote a fixed feature (identified at 413.4 nm on the two extracts of spectra), that is not masked and is significantly detected. This feature is not systematically present, at least on spectra where the redshift is correct
