A wide-field K-band survey. The luminosity function of galaxies
Abstract
We present the first determination of the near-infrared K-band luminosity function of field galaxies from a wide field K-selected redshift survey. The best fit Schechter function parameters are
M
∗
=−23.12+5log(h)
,
α=−0.91
, and
ϕ
∗
=1.66×
10
−2
h
3
Mp
c

. We estimate that systematics are no more than 0.1 mag in
M
∗
and 0.1 in
α
, which is comparable to the statistical errors on this measurement.
