The first plot (std_mos_grap1.png) is stored as Postscript file in $DFO_PLT_DIR.

CERTIF Reasons for rejection: - lack of signal; - saturated spectra (flat parts in raw data; not necessarily visible in processed data) if n_saturated > 0 check raw spectrum for flat parts. COMMENTS Chip 2 usually does not contain a spectrum. top [2009-07-30T07:17:12]         created by qcDocu v1.1, a tqs tool
