ALGORITHM Description of algorithms: median_master: median of central 1000x1000 pixels of master sigma_master: standard deviation of central 1600x1800 pixels of master structure: sigma_master minus standard deviation of central 1600x1800 pixels of difference from master and master shifted by 10x10, devided by sqrt(2) median_master is calculated by skyflat.prg, other parameters by pipeline recipe CERTIF Reasons for rejection: presence of stellar features in master frame; unusual structure if not representative COMMENTS quadrant 3 has always a specific large scale structure top [2016-03-11T12:31:12]         created by qcDocu v1.1.2, a tqs tool
