slit_to_gwa-1.0.0

NIRSPEC set of models from slit_frame to GWA.

Description

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

Schema Definitions ¶

This node must validate against all of the following:

This type is an object with the following properties:
- slits
  object Required

  \(P = quadrant * number_of_shutters_quadrant + slit_id\)
  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
