normal_shape

jwst.ipc.x_irs2.normal_shape(input_model, n=None, r=None, detector=None)[source]

Determine the shape of the ‘normal’ pixel data when excluding interleaved reference pixels.

Parameters:

input_modelJwstDataModel or ndarray: Either the input science data model or the data array from the input data model.
nint or None: If not None, this value will be used for the nrs_normal parameter. If n is None, the value will be obtained from the metadata for input_model, or, if this fails (e.g., if input_model is actually an ndarray), a default value will be used. None is the default.
rint or None: If not None, this value will be used for the nrs_reference parameter. See also the description for n. None is the default.
detectorstr or None: When input_model is a JwstDataModel, the detector name can be gotten from the metadata. If input_model is an ndarray, the detector name should be explicitly specified. For NIRSpec data, the value should be either “NRS1” or “NRS2”.

Returns:
