The following modules have only been partially implemented
- oimModel: Basic functionnalities for building model from all kind of components
- oimComponent: Many basics Fourier-based components, possiblity to build radial profile and images based components, import of image at fits format and a few advanced components (kinematic disk, fast-rotator)
- oimParam: Possibility to link parameters, normalize them and various interpolators in wavelength and time
- oimData: Interferometric data and basic wrapper for photometric/spectroscopic data
- oimDataFilter: Wavelength range cut and shift, data smoothing and binning, datatype selection, flagging based on criteria
- oimSimulator: Simulated data and chi2 computation with filtering
- oimFitter: Basic MCMC fitter based on emcee module.
- oimPlot: Various plots for oifits data (see examples below)
- oimUtils: Helpers for oifits format: retrieve baselines info, create new tables, manipulated data... )

Various example scripts are available in the
examplesdirectory.
This plot has been created with the createModelChromatic.py script:
Here is the resulting plot from the oimodel_Create_simulator_data.py script.
It plots data of a partly resolved binary created with:
- the ASPRO software from JMMC (including realistic noise)
- oimodeler using a shifted uniform disk + unresolved component
Here is a plot showing a model consisting of a fast rotating star plus a uniform disk.
Chromatic images of fast rotator are computed with an external function encapsulated into a oimodeler component.
The uniform disk is a simple Fourier-based component. The code is in the createCustomComponentImageFastRotator.py
