REDS

The REDS¹ extension is created by SURF as a general purpose repository of information that should be passed between SURF tasks.

It can contain the following entries:

BEAM_WT

The relative weight of the beams. Only used for PHOTOM observations. This is created by reduce_switch.

SKY

An NDF containing the estimate of the sky fluctuations. This is usually created by calcsky and is used by remsky to remove the sky fluctuations. The size of the NDF should match the size of the time axis in the main data array.

BOLWT

Relative weight of each bolometer. Created by setbolwt and used by rebin.
