In the infrared, as in the optical, the means of reporting source brightness and the units employed have varied considerably. In recent years however, 'magnitude' systems have been used less frequently, and the most popular unit for expressing brightness, both for point source fluxes and surface brightness, is steadily becoming the Jansky. We propose to adopt the Jansky as the standard flux unit for NICMOS in our documentation and in observer- oriented software. (Abstract of ISR NICMOS-014.)
