Northern JHK Standard Stars for Array Detectors
We report J, H, and K photometry of 86 stars in 40 fields in theNorthern Hemisphere. The fields are smaller than or comparable to a 4' x4' field of view and are roughly uniformly distributed over the sky,making them suitable for a homogeneous broadband calibration network fornear-infrared panoramic detectors. K magnitudes range from 8.5 to 14 andJ-K colors, from -0.2 to 1.2. The photometry is derived from a total of3899 reduced images; each star has been measured, on average, 26.0 timesper filter on 5.5 nights. Typical errors on the photometry are ~0.012mag.
