标题： Optical and Near-IR Field Luminosity Functions

摘要： 我们展示了从斯隆洛-APM红移巡天中选出的星系样本的光学和K带成像所得到的场星系b_J和K带光度函数（LFs）的初步测量结果。b_J光度函数与之前基于照相数据发表的结果一致。K带光度函数在12个星等范围内被估计，并且可以用一个Schechter函数很好地拟合，其暗端斜率α = -1.2。 显示英文摘要

摘要： We present preliminary measurements of the b_J and K-band luminosity functions (LFs) of field galaxies obtained from optical and K-band imaging of a sample of galaxies selected from the Stromlo-APM Redshift Survey. The b_J LF is consistent with that previously published from photographic data. The K-band LF has been estimated over a range of 12 magnitudes and is reasonably well fit by a Schechter function with faint-end slope alpha = -1.2.
