The Mauna Kea Observatories Near-Infrared Filter Set. I. Defining Optimal 1–5 Micron Bandpasses
A new Mauna Kea Observatories near-infrared (MKO-NIR) filter set is described, including techniques and considerations given to designing a new set of bandpasses that are useful at both midand highaltitude sites. These filters offer improved photometric linearity and in many cases reduced background, as well as preserving good throughput within the JHKLM atmospheric windows. MKO-NIR filters hav...

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 calibration for Vega determined by Co-hen et al. and Mégessier are consistent within the uncertainties, so that either absolute calibration may be used.

The isophotal wavelengths, flux densities, and AB magnitudes for Vega (a 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.

We present a description of a new 1–5 µm filter set similar to the long-used JHKLM filter set derived from that of Johnson. The new Mauna Kea Observatories Near-Infrared (MKO-NIR) filter set is designed to reduce background noise, improve photometric transformations from observatory to observatory, provide greater accuracy in extrapolating to zero air mass, and reduce the color dependence in th...
