Features

Modules:

• oimModel : Create models with various components as bricks
• oimComponent : component for building models
• oimParam : Component parameters and parameters interpolators
• oimData : Handle interferometric, spectroscopic and photometric data
• oimDataFilter : Filtering and modifying data (wavlengths range cut, smoothing, removing flags...)
• oimSimulator : Main class holding evertyhing together and producing final results :plots, tables...
• oimFitter : Define and perform model-fitting
• oimPlot : Plotting tools
• oimUtils : Various utility for optical-interferometry

:warning: Under Development :warning:

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... )

Examples

For more examples see: https://oimodeler.readthedocs.io/en/latest/examples.html

Various example scripts are available in the examples directory.

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
