NirissSOSSModel

class jwst.transforms.models.NirissSOSSModel(spectral_orders, models)

Bases: astropy.modeling.core.Model

NIRISS SOSS wavelength solution implemented as a Model.

Parameters:

• spectral_orders (list of int) – Spectral orders for which there is a wavelength solution.
• models (list of Model) – A list of transforms representing the wavelength solution for each order in spectral orders. It should match the order in spectral_orders.

Attributes Summary

inputs	x and y pixel coordinates and spectral order
outputs	RA and DEC coordinates and wavelength

Methods Summary

__call__(x, y, spectral_order[, …])	Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.
evaluate(x, y, spectral_order)	Evaluate the model on some input variables.
