Abstract
This report describes technical results obtained with the Arcetri near-infrared camera, ARNICA, mounted at three different telescopes from 1995 to 1998: TIRGO, the Nordic Optical Telescope, and the Vatican Advanced Technology Telescope.
For each telescope, we present estimates of the camera + atmosphere efficiency, point- and extended-source sensitivity, telescope emissivity, and mean atmospheric extinction coefficients. We also use data from January, 1995 to January, 1998 to analyze ARNICA's bad pixels and their change with time.
