The Mauna Kea Observatories Near‐Infrared Filter Set. I. Defining Optimal 1–5 Micron Bandpasses

Abstract: A new MKO-NIR infrared filter set is described, including techniques and considerations given to designing a new set of bandpasses that are useful at both mid-and high-altitude sites.These filters offer improved photometric linearity and in many cases reduced background, as well as preserve good throughput within the JHKLM atmospheric windows. MKO-NIR filters have already been deployed within a number of instruments around the world as part of a filter consortium purchase to reduce the unit cost of filters. Th… Show more

“…The near through mid-IR wavelengths chosen (e = 1250 nm, 1650 nm, 2200 nm, 2400 nm) are within the transparency windows of air [20]. We find that the nonlinear response is quite dispersionless over the range of wavelengths investigated, except near e=400 nm, consistent with a simple model for the third-order nonlinear susceptibility developed by Bishop [21].…”

“…We calibrated the photometric measurements with respect to those of 27 (J) and 23 (H) nearby stars with magnitudes 0.2-2.0 mag brighter than those of HD 203030B and with precise photometry (±0.02-0.06 mag) from 2MASS (Skrutskie et al 2006). We converted the 2MASS magnitudes of these calibration stars to the MKO system (Simons & Tokunaga 2002) following the relations given in Hodgkin et al (2009), and fit first-order polynomials between the instrumental and MKO magnitudes of the calibrators. Finally we used these fits to calibrate the magnitude of HD 203030B.…”
