The Mauna Kea Observatories near-infrared filter set. III. Isophotal wavelengths and absolute calibration

The isophotal wavelengths, flux densities, and AB magnitudes for Vega (alpha Lyr) are presented for the Mauna Kea Observatories near-infrared filter set. We show that the near-infrared absolute calibrations for Vega as determined by Cohen et al. and Megessier are consistent within the uncertainties, so that either absolute calibration can be used.
