Description:
A
simple PICARD recipe to calculate the noise equivalent flux density (NEFD) from reduced
SCUBA-2 images. The NEFD image is written as an NDF component (called nefd) to the
original file (or a calibrated version thereof) under the .more.smurf hierarchy.
Notes:
-
The input data should be calibrated in mJy/beam, but will be calibrated if necessary.
-
The output file from this recipe will have suffix _cal if the input data were uncalibrated. The NEFD
image will be in this file (though see KEEPFILES below).
-
The median and effective NEFD are printed to the screen.
Available Parameters :
The following
recipe parameter can be set via the -recpars option:
KEEPFILES
Flag to denote whether to write
the NEFD image as an NDF component in the output file. Default is 1 (yes). If set to 0 the the median
and effective NEFDs will be derived and printed to the screen only; the image will not be saved.
Display
None.
