Near-infrared photometry of stars
Results are presented of infrared photometric observations performed oncomparison stars during a monitoring of long-period variables. Theseobservations, spread over a lapse of about 5 years, are used to derivethe J, H, and K magnitudes of 54 stars in the photometric systemdescribed by Koornneef (1983). The 1950.0 coordinates, spectral types,visual magnitudes, average magnitudes, and the number of observationsare given for each object.
