Controls the determination of multiple background signals PCA.NOISELIM
"
pca.noiselim"
times the noise level it
had before removal of the PCA model, then the bolometer is flagged as bad until the next iteration.
This usually happens for bolometers that appear to be "
unique"
for some reason (i.e. look
completely unlike other bolometers). In such cases one of the PCA components will be nearly
identical to the bolometer, and so leave no significant residuals after subtraction of hte
PCA model. Note, this parameter should normally be set to zero if the PCA model occurs
before the COM model within pareameter "
modelorder"
. This is because the PCA model
will then remove the typically huge common mode, resulting in an apparent huge fall
in noise in all bolometers. This would cause all bolometers to be rejected if the default
value is used for pca.noiselim. [0.1]
