Query: The Mauna Kea Observatories Near-Infrared Filter Set. II. Specifications
  for a New JHKL'M' Filter Set for Infrared Astronomy   We present a description of a new 1--5 $\mu$m 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 the extinction coefficient in photometric
reductions. We have also taken into account the requirements of adaptive optics
in setting the flatness specification of the filters. A complete technical
description is presented to facilitate the production of similar filters in the
future.
