The Archive is formed with all files measured with ARcetri Near Infrared CAmera ( ARNICA). Each files contains (in FITS format) or a single exposure or the mean of single exposures taken at the same telescope position. The filer used can be either a Johnson broad band infrared filter (J, H, K), or a narrow band filter (see ARNICA) page for details). Most measures was acquired at the TIRGO telescope, while a smaller sample cames from the few telescopes Arnica was ported to (WHT, NOT, VATT and TNG). All frame are in FITS format and are 256x256 pixels in size. The archive contains more than 250.000 frames. Most files belongs to a compound measure (we call them "a mosaic").
