Comparison between masking in the SPG pipeline (top) and transient-correction pipeline (bottom). Signal is blue and masked frames are represented as red circles. The SPG pipeline masks a few deviant frames as GLITCHES, while the transient-correction pipeline masks frames either as GLITCHES or as UNCORRECTED. As a result, the signal from the SPG pipeline will contain unmasked residuals of big transients, while the transient-correction pipeline will either correct the transients or masked them completely. This leads to a big reduction of noise in the final reduction with respect to the product from the SPG pipeline.
