get_soss_wavemaps

jwst.extract_1d.soss_extract.pastasoss.get_soss_wavemaps(pwcpos, subarray='SUBSTRIP256', refmodel=None, spectraces=False, orders_requested=None)

Get the SOSS wavelength maps and (optionally) spectraces.

Parameters:

pwcposfloat

The pupil wheel position angle, e.g., as provided in the FITS header under keyword PWCPOS. Values are expected to be within +/- 0.25 degrees of the commanded position (245.76 degrees).

subarraystr, optional

The subarray name, one of ‘SUBSTRIP256’, ‘SUBSTRIP96’, or ‘FULL’.

refmodelPastasossModel, optional

The reference model for the SOSS extraction. If not set, it will be fetched from CRDS.

spectracesbool, optional

If True, return the interpolated spectraces as well.

orders_requestedlist

A list of the spectral orders requested for extraction. If None, all orders in the reference file will be used.

Returns:

wavemapsndarray

The 2D wavemaps. Will have shape (n_orders, array_x, array_y) with orders 1, 2, etc. being the elements of the first dimension. Wavemaps for all orders defined in the reference file will be returned.

tracesndarray, optional

The corresponding 1D traces (if spectraces is True).
