gwa_to_slit-1.0.0

NIRSPEC set of models from GWA to slit_frame.

Description

This model is used by the NIRSPEC WCS pipeline. It maps slit to the transform from the Grating Wheel Assembly (GWA) to the coordinate frame of the slit, where (0, 0) is the center of the slit.

Schema Definitions ¶

This node must validate against all of the following:

This type is an object with the following properties:
- slits
  object Required
  An array with slit numbers. The slit number is computed from the quadrant and the slit ID in this quadrant using
  
  \(P = quadrant * number_of_shutters_quadrant + slit_id\)
  This node must validate against any of the following:
  
  array
  No length restriction
  
  Items in the array must be any of the following types:
  
  array
  No length restriction
  
  number
  
  tag:stsci.edu:asdf/core/ndarray-*
- models
  array Required
  A compound model transferring positions at the GWA to position in the slit frame.
  
  No length restriction
