PARAMETERS:
Sigma=6 -- All pixels in the flat off (dark)
that are way above the median value
are set to NaN *** The selection is
done in the following way :
subtract a low-pass to the flat_off
to keep only single 'hot' pixels,
and select all pixels more than 6
sigma (estimated through
robust_sigma) of the median-filtered image.
DESCRIPTION:
Produces calibration given a list of fits files with flats,
darks and sky exposures
OUTPUT FILES:
flat_red_<suffix>.fits
flat_blue_<suffix>.fits
sky_red_<suffix>.fits
sky_blue_<suffix>.fits
Note: This code has skycube<color,suffix>.fits writeto commented.
