Slit2Msa

class jwst.transforms.Slit2Msa(slits, models)[source]

Bases: astropy.modeling.core.Model

NIRSpec slit to MSA transform.

Parameters:
  • slits (list) – A list of open slits. A slit is a namedtupe, 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, x and y coordinates within the virtual slit.
outputs x and y coordinates in the MSA frame.
