摘要
We present a new determination of the luminosity and mass functions for field stars at the bottom of the main sequence as the first results from a 320 deg2 survey based on both optical and near-infrared photometry. The luminosity and mass functions are determined with an order of magnitude higher precision than previous studies have been able to achieve. We find no evidence for a mass function steepening toward the H-burning limit.
