jwst.straylight.correct_mrs_modshepard(input_model, slice_map, roi, power)[source]¶ Straylight correction using a modified Shepard algorithm.
Corrects the MIRI MRS data for straylight using a Modified version of the Shepard algorithm. Straylight is determined using an inverse distance weighting function. The inverse distance weighting is determined by module
shepard_2d_kernel(roi,power).- Parameters
input_model (
IFUImageModel) – Science data to be corrected.slice_map (ndarray) – Holds the pixel region mask for the correction. slice = (band*100+slice#) gap = 0
roi (float) – Region of influence (size of radius)
power (float) – Exponent of Shepard kernel.
sci_ngroups (int) – Number of groups in input data.
- Returns
output – Straylight-subtracted science data.
- Return type
