SQM(-L) mag/arcsec
SQM stands for Sky Quality Meter. It's a small device that can measure sky quality ie. darkness. Color levels used in the maps. The first column gives the ratio between the artificial brightness and the natural background sky brightness (assumed to be 174 mcd/m2 ); the second column gives the artificial brightness (mcd/m2 ); the third column gives the approximate (that is, assuming a natural background of 22 mag/arcsec2 ) total brightness (mcd/m2 ); and the fourth and fifth columns give the colors.
