Notes. Ncont/4 deg2 is the number of contaminants contained within a solid angle of 4 deg2 along the l.o.s. to the galaxy. The last 4 columns list the fraction of contaminants retained when using only the velocity criterion, the line criterion, when applying both, and applying both relaxing the velocity selection to 4-σ.
