handle_bandpass

jwst.ami.utils.handle_bandpass(bandpass, throughput_model)

Determine what to do with the input bandpass.

If user-provided, return in format expected by code. If none, fetch filter throughput and combine with flat spectrum to produce appropriate array.

Parameters:

bandpassSynphot spectrum or array, or None

User-defined bandpass to override filter/source. If bandpass is an array, wavelengths must have units of meters.

throughput_modelThroughputModel

Datamodel containing filter throughput info. Wavelengths are in Angstroms. Will not be used if bandpass is not None.

Returns:

bandpassarray

Array of weights, wavelengths used to generate model. Wavelengths are in meters.
