COM.CORR_ABSTOL

Controls the rejection of bad samples from the COM estimate

Description:

Gives the absolute lower limit of acceptable correlation between a bolometer time-stream and the common-mode. This is the first of a set of " com. <xxx >" parameters that control the rejection of bad detectors based on the gain and correlation coefficients for the fit of the common-mode signal to each detector (good at identifying bolo signals with bizarre gains, or shapes if they have for example steps in them). These are basically sigma-clippers; outliers are removed at the given threshold and then new means and sample standard deviations are measured until convergence. The time axis is divided up into one or more equal sized boxes, and a separate fit is performed for each box. If you wish to completely disable the flagging of outlier bolometers compared with the common-mode, simply set com.noflag=1. The flags may be frozen after a specified number of iterations - see parameter "com.freeze_flags" . [0.2]
