NORTHERN JHK STANDARD STARS FOR ARRAY DETECTORS

We report J, H, and K photometry of 86 stars in 40 fields in the North ern Hemisphere. The fields are smaller than or comparable to a 4' x 4' held of view and are roughly uniformly distributed over the sky, maki ng them suitable for a homogeneous broadband calibration network for n ear-infrared panoramic detectors. K magnitudes range from 8.5 to 14 an d J-K colors, from -0.2 to 1.2. The photometry is derived from a total of 3899 reduced images; each star has been measured, on average, 26.0 times per filter on 5.5 nights. Typical errors on the photometry are similar to 0.012 mag.
