QC1PARAM |
QC1 parameters written in QC1 database:
QC1 DB names: master1/2/3/4/_median | master1/2/3/4_mean | master1/2/3/4_stdev | master1/2/3/4_min |
master1/2/3/4_max | master1/2/3/4_ron | master1/2/3/4_slope_x | master1/2/3/4/_slope_y
All parameters are calculated by the pipeline recipe.
|
|
ALGORITHM |
Description of algorithms:
master1/2/3/4/_median: median in the 1/2/3/4/quadrant of the master bias
master1/2/3/4/_mean: mean in the 1/2/3/4/quadrant of the master bias
master1/2/3/4/_stdev: standard deviation of the master bias in quadrant1/2/3/4
master1/2/3/4/_min: minimum value in the 1/2/3/4/quadrant of the master bias
master1/2/3/4/_max: maximum value in the 1/2/3/4/quadrant of the master bias
master1/2/3/4/_ron: read-out-noise in 1/2/3/4/quadrant from difference images of each adjacent
pair of biases in the input dataset in randomly placed windows
master1/2/3/4/_ronerr: read-out-noise error in 1/2/3/4/quadrant from difference images of each adjacent
pair of biases in the input dataset in randomly placed windows
master1/2/3/4_slope.x: average horizontal slope of master bias in quadrant1/2/3/4
master1/2/3/4_slope.y: average vertical slope of master bias in quadrant1/2/3/4
|
|
CERTIF |
Reasons for rejection:
unusual high bias level or read-out noise, change of structure, lower DATANCOM value
