PCD at sample level (SP) for the spectrometers. Each unsigned short integer is composed of the following bit flags: bit 0: FL_sat(k,L,f) - saturation flag for the lower band (0 = no saturation; 1 = saturated); bit 1: FL_sat(k,C,f) - saturation flag for the central band (0 = no saturation; 1 = saturated); bit 2: FL_sat(k,U,f) - saturation flag for the upper band (0 = no saturation; 1 = saturated); bit 3: FL_bad(k,L) - bad pixel flag for the lower band (0 = no bad pixel in the sample; 1 = at least one bad pixel); bit 4: FL_bad(k,C) - bad pixel flag for the central band (0 = no bad pixel in the sample; 1 = at least one bad pixel); bit 5: FL_bad(k,U) - bad pixel flag for the upper band (0 = no bad pixel in the sample; 1 = at least one bad pixel); bit 6: FL_cr(k,L,f) - cosmic ray detection for lower band (0 = no cosmic ray detected in the sample; 1 = one cosmic ray in the sample); bit 7: Fl_cr(k,C,f) - cosmic ray detection for the central band (0 = no cosmic ray detected in the sample; 1 = one cosmic ray in the sample); bit 8: FL_cr(k,U,f) - cosmic ray detection for the upper band (0 = no cosmic ray detected in the sample; 1 = one cosmic ray in the sample); bit 9-10: FL_bg(k,f) - background data flag (0 = central background computed with no flagged sample; 1 = less than 25% flagged samples; 2 = less than 50% flagged samples; 3 = more than 50% flagged samples); bit 11-12: FL_ft(k,f) - full transmission computation (0 = no problems identified; 1 = reference star spectrum value is zero; 2 = one of the spatial bands is flagged for saturation); bit 13: FL_off(k) - pixel is in an invalid spectral range (0 = pixel is in a valid range; 1 = pixel is in an invalid spectral range); bit 14: FL_rsp(k,f) - pixel has been computed with flagged data during resampling process (0 = no problem; 1 = current data computed with flagged data); bit 15: Not used anymore.

PCD at sample level (FP) for the fast photometers. The first integer refers to photometer 1, the second to photometer 2. Each unsigned integer contains the following information: bit 0: FL^FP_sat(fc,f,fp) - photometers saturation flag (0 = no saturation; 1 = saturated sample); bit 1-15: not used.
