Fig. 4

Comparison between VUDS spectroscopic redshifts before and after the inspection of the tiger team (TT) of redshifts measured after a first measurement pass (see text). Only objects with a change are considered here. Represented in this figure are about 10% of all objects, including those with a redshift change (6%) or a flag change (4%). Red circles represent objects for which the reliability flag was downgraded after the inspection of the tiger team; filled cyan circles are objects with upgraded flags, blue triangles are objects retaining the same flag. Objects with undetermined redshifts (flag = 0) before the TT work are placed at zbefore = 8 and are represented with orange star symbols. Objects with undetermined redshifts after the TT work (either keeping their original undetermined status or those that the TT decided to downgrade) are the red circles at zafter = 8.
