DATA: 2 nuits d'observations Pionier:

OIFITS 1: -- * Summary of data for current file : Total nb of telescopes 4 nb of telescopes at each time (from closure phase data): 4 nb of bases at each time (n_bases_per_nuplet): 6 nb of closures at each time (n_clotures_per_nuplet): 3 nb of wavelengths : 7 nb of distinct times: 10 => nb of VIS measurements per base (n_nuplets): 70 ==> Total nb of visibility measurements : 420

OIFITS 2: * Summary of data for current file : Total nb of telescopes 4 nb of telescopes at each time (from closure phase data): 4 nb of bases at each time (n_bases_per_nuplet): 6 nb of closures at each time (n_clotures_per_nuplet): 3 nb of wavelengths : 7 nb of distinct times: 9 => nb of VIS measurements per base (n_nuplets): 63 ==> Total nb of visibility measurements : 378

Nombre total de points de visitilité: *** Total number of visibility measurements over all files : 798

Lignes de commandes lancées sur WISARD:

guess = reconstruction nbiter=100 threshold=1.e-6 fov=7.0 np_min=64 scale_factor=3.0d; aux_output=1; t0=SYSTIME(/SECONDS ) ; time reference for measuring duration of computation reconstruction = WISARD(data, NBITER = nbiter,$ GUESS = guess, FOV = fov*onemas, NP_MIN = np_min, THRESHOLD=threshold, $ AUX_OUTPUT=aux_output, SCALE = scale_factor/(NP_min)^2, DELTA = 1D,/DISPLAY, WHITE=0, LUT=13)

Les 100 itérations ont été réalisées après ~4 minutes de calcul sur un MacBook? Pro d'il y a 2 ans, sous Snow Leopard version 10.6.8, avec IDL 8.0 en 64 bit.
