Gwa2Slit

class jwst.transforms.Gwa2Slit(slits, models)[source]

Bases: astropy.modeling.core.Model

NIRSpec GWA to slit transform.

Parameters:
  • slits (list) – A list of open slits. A slit is a namedtupe of type Slit Slit(“name”, “shutter_id”, “xcen”, “ycen”, “ymin”, “ymax”, “quadrant”, “source_id”, “shutter_state”, “source_name”, “source_alias”, “stellarity”, “source_xpos”, “source_ypos”])
  • models (list) – List of models (Model) corresponding to the list of slits.

Attributes Summary

inputs Name of the slit and the three angle coordinates at the GWA going from detector to sky.
outputs Name of the slit, x and y coordinates within the virtual slit and wavelength.

Methods Summary

__call__(name, angle1, angle2, angle3[, …]) Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.
evaluate(name, x, y, z) Evaluate the model on some input variables.
get_model(name)
