Abstract
J-PAS survey consists of an 8000 square degree photometric sky survey with a set of 54 narrow-band, 2 mediumband and 1 broad-band filters. The main goal is to produce a photo-redshift catalog of 15 millions red, earlytype galaxies with a precision (z) 0:003(1 + z) to measure the Baryonic Acoustic Oscillation (BAO). Such precision requires specific care in the photometric calibration survey. This contribution presents the calibration protocol developed at CEFCA for the J-PAS data and to be applied from its first day. An auxiliary telescope JAST/T80 will perform an initial survey, J-PLUS, available before J-PAS, to create a set of flux calibrated stars in all J-PAS fields. Seven reference stars were already chosen to calibrate in flux the J-PLUS survey. J-PLUS 12-filter system was also specifically optimized to retrieve stellar parameters, T, log(g), [Fe/H], through the fitting of flux calibrated models. J-PLUS will be used as the standard network of flux calibrated stars to create synthetic spectro-photometry for J-PAS 56-filter system and to achieve the 1% photometric precision required for BAO measurements.
