EFOSC2 imaging Bugs for Dave/Cosimo to check/correct in purple / Bugs for Stefano to correct in next version of pipeline in red ESO request that the EFOSC2 acquisition images are submitted as science files. Hence we need to make sure the photometric keywords are set correctly, there are a few bugs in these and in the photometric science files. There are 1152 acquisition images in /data/psdb2data1/pessto_eso_phaseIII/validated_pessto_files/efsoc/spectra There are also 1309 photometric science images. Problem 1 99 files have ABMAGLIM = INF.0 or 9999.0 set Cause : the median background (MBKG) is a negative number, hence Eqn A.7 takes sqrt of -ve number 143 files do not have PHOTZP set, have ABMAGLIM=9999.0 and a nonsense value for ABMAGSAT These are all unfiltered images, so we should not submit those as science files, as they are uncalibrated. Easy purge of files : if FILTER = Free or HIERARCH ESO INS FILT1 NAME = Free than do not submit these as science files. (Dave to always do this in the future before SSDR is sent to ESO - but data reducers to check these and purge during the reduction proces ). Problem 3 In equation A.7 (in PESSTO paper), AGMAGLIM is defined. However if the meadian background is negative, then this will be sqrt(-ve number). This equation assumes images are background limited. For short exposures the MBKG can be negative, due to bias drifts and being read noise dominated. Solution is to replace the old equation A.7 with the general form which accounts for frames which are read noise dominated. The new version of the paper (v13 and above) has the new equation. Stefano - to correct this calculation in the next version of the pipeline SOFI imaging 213 SOFI science images.
