Abstract
Two different simple measurements of galaxy star formation rate withdifferent timescales are compared empirically on 156,395 fiber spectraof galaxies with r<17.77 mag taken from the Sloan Digital Sky Surveyin the redshift range 0.05-4h3Mpc-3Gyr-1 atredshift z~0.1. These events are taking place in the field; the K+Agalaxies found in this study do not primarily lie in the high-densityenvironments or clusters typical of bulge-dominated populations.
