dark_grap1.png left: averaged central rows and columns of all quadrants of master dark in e-/hr/pix (median filtered with window size of 7 pixels) clockwise from top left: Y200...300, X450...550, X1450...1550, Y700...800 right: histogram: all pixel values of master dark in log frequency histogram; should show dominant peak with Gaussian shape (which translates to parabola shape in this log freq diagram) top panel: date; name of analyzed master dark frame (left, red); number of frames, exposure time, conversion factor (right, black) bottom panel: some QC1 parameters- median_master and sigma_master in e-/px/hr dark_disp1.png full display of master frame | ||||||||||||||||||||||
| QC1PARAM |
QC1 parameters written into QC1 table: QC1db names: datancom | dark_avg | sigma_dark_avg | dark_A(BCD) | sigma_dark_A(BCD) | median_master | sigma_master FITS key names: DATANCOM | (dark_qc.prg) | (dark_qc.prg) | (dummy) | (dummy) | (dark_qc.prg) | (dark_qc.prg) QC1 params created by pipeline: datancom, median_master, sigma_master QC1 params created by this procedure: all except datancom, median_master, sigma_master | ||||||||||||||||||||||
| ALGORITHM |
Description of algorithms: dark_avg: median level of master dark averaged over X200...1800, Y400...800 in e-/hr/pix, excluding values outside +-50 sigma_dark_avg: RON/exp.time*3600 in e-/hr/pix median_master: statistics (median) of full master frame sigma_master: statistics (std_dev) of full master frame | ||||||||||||||||||||||
| CERTIF |
Reasons for rejection: - unusual structure; - non-Gaussian shape of histogram; - DATANCOM lower than usual (3), especially if N=3 version nearby in time | ||||||||||||||||||||||
| COMMENTS | QC1 DB columns dark_A(BCD) and sigma_dark_A(BCD) contains always "none". | ||||||||||||||||||||||
