background_sub

jwst.background.background_sub.background_sub(input_model, bkg_list, sigma, maxiters)

Subtract background signal from an exposure.

This will be done by subtracting the average of one or more background exposures from it.

Parameters:

input_modelImageModel

Input target exposure data model. Updated in place.

bkg_listlist

Filename list of background exposures.

sigmafloat

Number of standard deviations to use for both the lower and upper clipping limits.

maxitersint or None

Maximum number of sigma-clipping iterations to perform.

Returns:

bkg_modelImageModel

Background data model

input_modelImageModel

Background-subtracted target data model.
