nrs_wcs_set_input

jwst.assign_wcs.nrs_wcs_set_input(input_model, slit_name)

Make a WCS object for a specific slit or slice.

Transforms in the new WCS do not require slit IDs on input and do not report slit IDs in the output.

If there is a compound bounding box set for the input model, a bounding box will be set for the slit WCS. Otherwise, the bounding box will be None.

Parameters:

• input_model (JwstDataModel) – A datamodel that contains a WCS object for the all open slitlets in an observation.

• slit_name (int or str) – Slit.name of an open slit.

Returns:

wcsobj – WCS object for this slit.

Return type:
