- jwst.lib.set_telescope_pointing.calc_wcs(t_pars: TransformParameters)[source]
Calculate WCS.
Given observatory orientation and target aperture, calculate V1 and Reference Pixel sky coordinates.
- Parameters:
- t_pars
TransformParameters The transformation parameters. Parameters are updated during processing.
- t_pars
- Returns:
