Abstract
During a regular night dedicated to the survey, less than 10 photometric standard stars in each band can be observed. This is enough to check the photometric quality of the night but not to define the DENIS photometric system. For that, 1 or 2 nights per month are dedicated to photometry in order to determine accurately the atmospheric extinction coefficients, the zero-points, and the transformation coefficients between the DENIS instrumental system and other photometric systems. In this paper, the main steps of the DENIS photometric calibration (development of the standard star catalogue, observing strategy, data processing, etc.) are reviewed and preliminary results based on a few calibration nights are presented.
