The Mauna Kea Observatories Near‐Infrared Filter Set. III. Isophotal Wavelengths and Absolute Calibration

The isophotal wavelengths, flux densities, and AB magnitudes for Vega (α 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 Mégessier are consistent within the uncertainties, so...

Description
Summary:The isophotal wavelengths, flux densities, and AB magnitudes for Vega (α 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 Mégessier are consistent within the uncertainties, so that either absolute calibration can be used.
