DCTHRESH

Control the cleaning of DC steps in bolometer time streams

Description:

The SNR threshold at which to detect DC steps. Note, this refers to the noise level in the bolometer data after it has been smoothed with a median filter of width given by parameter "dcsmooth" . In order to find the equivalent threshold in the unsmoothed data, multiply the dcthresh value by 1.25/sqrt(dcsmooth). For instance, the default values for dcsmooth (50) and dcthresh (25) correspond to a threshold of 251.25/sqrt(50) = 4.4 sigma in the unsmoothed data. Only used if parameter "dcfitbox" is non-zero.
