PCA.BACKOFF

Controls the determination of multiple background signals

Description:

This parameter controls whether the residuals after subtraction of the PCA model should be flattened by the removal of a quadratic background from each bolometer. Disabling this option speeds up the PCA model considerably, and seems to produce little effect if the PCA model occurs after the COM model within the model order. [0]
