The luminosity function of A2199 is consistent with a single Schechter function to Mr=-15.6+5log(h70) with a faint-end slope of alpha=-1.13±0.07 (statistical). The LF in Virgo extends to Mr~-13.5∼M*+8 and has a slope of alpha=-1.28±0.06 (statistical). Description: We obtained optical spectroscopy of A2199 with MMT/Hectospec in 2007 July under marginal observing conditions. File Summary:
