Description:
Summit-pipeline recipe for processing NOISE observations. The bolometer power spectra are
calculated and the relative power at two (user-specifiable) frequencies is calculated. If this ratio
exceeds a critical value, defined by the MASKVAL parameter below, the bolometer is marked as
bad.
The outcome of this recipe is a noise image and bad-bolometer mask for each subarray which is stored
in the calibration system.
Notes:
-
This recipe only works with raw time-series data.
-
See the documentation for _CREATE_BAD_BOLO_MASK_ for further parameters which may be
specified to determine bad bolometers.
-
Bad-bolometer mask file names are stored in index.mask.
Available Parameters :
The following
parameters can be set via the -recpars option:
BESTBOL_PERCENT
The number of bolometers
expressed as a percentage which should be used to create a bad-bolometer mask.
Display
The
average bolometer power spectrum is displayed in a Kapview window. The noise map and
corresponding histogram are displayed in a different Kapview window (each subarray is displayed in
different window).
