K-band galaxy luminosity function from 2MASS

We measured the K-band luminosity function using a complete sample of 4192 morphologically typed 2MASS galaxies with {mu}Ks=20mag/arcsec^2^ isophotal magnitudes 7本研究采用包含4192颗经形态学分类的2微米全天巡天（Two Micron All-Sky Survey，2MASS）星系的完整样本，以μKs=20星等/平方角秒的等照度星等为基准，测定了K波段光度函数。
