class jwst.ami.mask_definition_ami.NRMDefinition(nrm_model, maskname='jwst_ami', chooseholes=None)[source]

Defines the geometry of the NRM mask.

Set attributes of NRMDefinition class.

Get hole centers and other mask geometry details from NRMModel, apply rotations/flips as necessary and set them as attributes.

Parameters:

nrm_modelNRMModel: Datamodel containing NRM reference file data
masknamestr: Identifier for mask geometry; default ‘jwst_ami’, optional
chooseholeslist: None, or e.g. [‘B2’, ‘B4’, ‘B5’, ‘B6’] for a four-hole mask, optional If None, use real seven-hole mask

Methods Summary

read_nrm_model(nrm_model[, chooseholes])

Calculate hole centers with appropriate rotation.
