The data resulting from the prereduction are not summoned. As we saw, it is absolutely necessary to identify the cosmic rays for elimination. The coaddition was carried out using the parcelling IRAF developed in STScI. It produces the coadditionnées images and eliminates the cosmic rays.
Finally, the images were indexed in our data base. The files containing the images were separate to produce individual images corresponding to the 4 CCDs composing the mosaic.
As we have it, the supernovæ all were followed to the assistance Planetary Camera. These is thus specifically the CCD which was studied. In the continuation we present the specific software of reduction HuPhot which we developed with the LPNHE to carry out the photometry of the supernovæ of our batch. These software tools (coded in C++) were built on limps with ToADS tools which we presented at the time of the chapter of detection. They use mainly the tools for FITS and list image processing of them of photometry.
Moreover, this tool uses libraries ROOT Contents Julien Raux 2004-05-04
