Wide-Angle Near-Infrared Surveys of Local Galaxies
Recently, it has become possible to perform wide-angle galaxy surveys at near-infrared (2.2µm) wavelengths. Such surveys cover limited areas to magnitude limits similar or fainter than that achieved by the DENIS or 2MASS projects. Therefore, the resulting number-magnitude counts can be used to calibrate these datasets. Also, due to the relatively bright magnitude limit of these wide-angle surveys, spectroscopic observations are straightforward and hence, one could construct the local near-ir luminosity function (LF) of galaxies. This could be used to predict the space density of galaxies expected from DENIS or 2MASS, providing reliable control samples for these larger studies.
