ETC-42 Exposure Time Calculator: Evolution and New Functionalities
Résumé
We developed at CeSAM (Centre de donnees Astrophysiques de Marseille) ETC-42, an Exposure Time Calculator compliant with Virtual Observatory standards. ETC-42 has been designed to facilitate the integration of new sites, instruments and sources by the user. It is not instrument-specific, but is based on generic XML input data. It is used in several project implementations (EUCLID, PFS, IRIS, WISH, EELTs) covering a wide wavelength range, from NIR to UV. The previous release has been optimized to achieve gain of computation time. New functionalities for automatic input parameterization have been added to target specific instrumental configuration and to give an increased level of user-friendliness. This article describes the new functionalities : fixtures, sdaptive optics, Fabry Perot implementation and two new builder tools to create Telescope transmission curves and sky brightness tables. And, in order to facilitate the integration to the Virtual Observatory environment, VO drag and drop functionality is now available.
