V2V3ToIdeal¶

class jwst.transforms.models.V2V3ToIdeal(v3idlyangle, v2ref, v3ref, vparity, name='V2idl', **kwargs)[source]¶

Bases: astropy.modeling.core.Model

Performs the transform from telescope V2,V3 to Ideal coordinate system. The two systems have the same origin - V2_REF, V3_REF.

Note: This model has no schema implemented - add if needed.

Attributes Summary

`inputs`	coorinates in the telescope (V2,V3) frame.
`outputs`	x and y coordinates in the telescope Ideal frame.
`param_names`
`v2ref`
`v3idlyangle`
`v3ref`
`vparity`

Methods Summary

__call__(v2, v3[, model_set_axis, …]) Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.

evaluate(v2, v3, v3idlyangle, v2ref, v3ref, …)

param xidl, yidl:
	Coordinates in Ideal System [in arcsec]
