Apply the image plane algorithm (LG-PLUS) to an AMI exposure.
- Parameters:
- input_modeldata model object
AMI science image to be analyzed
- throughput_modeldata model object
Filter throughput data
- nrm_modeldata model object
NRM model data
- oversampleint
Oversampling factor
- psf_offsetstr (two floats)
PSF offset values to use to create the model array
- rotsearch_parametersstr (‘start stop step’)
Rotation search parameters
- bandpasssynphot spectrum or array
Synphot spectrum or array to override filter/source
- usebpbool
If True, exclude pixels marked DO_NOT_USE from fringe fitting
- firstfewint
If not None, process only the first few integrations
- chooseholesstr
If not None, fit only certain fringes e.g. [‘B4’,’B5’,’B6’,’C2’]
- affine2duser-defined Affine2D object
None or user-defined Affine2d object
- run_bpfixbool
Run Fourier bad pixel fix on cropped data
- Returns:
- oifitsmodelAmiOIModel object
AMI tables of median observables from LG algorithm fringe fitting in OIFITS format
- oifitsmodel_multiAmiOIModel object
AMI tables of observables for each integration from LG algorithm fringe fitting in OIFITS format
- amilgmodelAmiLGFitModel object
AMI cropped data, model, and residual data from LG algorithm fringe fitting
