  1. Production N0/N1/N2 Status of current software Proposed evolutions foreplanned production CoRoT S.C. - 24/09/07 - S.Chaintreuil

  2. Status of current software • All N1 products are able to be produced (except exo imagettes) • Initialization data • auxiliary products : windescriptor, templates, masks • high resolution PSF • surfaces de correction • Common products • datation (OBT, GPS) • orbit_events, ephemeris • N1 seismology products • offset, backgrounds, light curves, imagettes • N1 exo products • offset, backgrounds 32s et 512s, chromatic et monochromatic light curves, 32s et 512s, (imagettes) • Outliers are removed in offset and background data • V1.0 : Outliers are « marked » and SAA informations are inserted into star light curves • V1.1 : SAA informations are inserted into star light curves and outliers are replaced using method 2 (médiane ou moyenne glissante) CoRoT S.C. - 24/09/07 - S.Chaintreuil

  3. Two types of N1 products • N1 for « alarm » • offset corrections • Background corrections using « median background light curves » calculated as the median of similar background light curves (will be implemented for LRa01) • No jitter corrections, no outliers corrections • N1 for N2 • current version (1.0) • offset corrections, background corrections (bright pixels not removed), jitter corrections, SAA flag inserted, outliers marked • version 1.1 (if required) • offset corrections, background corrections (bright pixels not removed), jitter corrections, SAA flag inserted, outliers marked • Version 2 : will probably use new modules processing the whole run • 1 or 2 softwares ? still in discussion CoRoT S.C. - 24/09/07 - S.Chaintreuil

  4. Production • Currently, all N1 products are generated at LESIA • N1 products for alarm will be produced at CNES (04/2008) or at LAM • N1 products for N2 will be produced at LESIA then at CNES (when/if methods are stable) • N2 products will be generated at LESIA CoRoT S.C. - 24/09/07 - S.Chaintreuil

  5. Calendrier • introduire les corrections de pixels brillants sur les fonds de ciel pour les 4 premiers runs • fin septembre • produire des N1 exo au fil de l’eau en vue de la détection des alarmes au LAM • dès le début de LRa01 • distribuer une première version des données N2 des 2 voies de IRa01 • début décembre • distribuer une première version des données N2 des 2 voies de SRc01 • début janvier • préparer l’introduction des corrections de long terme dans la chaîne de production des N1 en vue des N2 • mars-avril 2008 CoRoT S.C. - 24/09/07 - S.Chaintreuil

  6. Planning CoRoT S.C. - 24/09/07 - S.Chaintreuil
