Calnic C is an IDL program which identifies objects on a direct image and classified them as stars or galaxies using a neural network approach implemented (Using SExtractor program (Bertin & Arnouts, 1996, A & A Suppl. 117, 393)). The position of the object is used to extract spectra from a grism image of the same region.
The software is currently being developed at the Space Telescope - European Coordinating Facility.
