OITOOLS is an environment tools to load, visualize, model-fit and image optical interferometry data coming from CHARA, NPOI and VLTI, written in Julia by GSU Professor Fabien Baron. OITOOLS allows you to simulate CHARA observations and save them as an OIFITS file. For model fitting, OITOOLS allows you to fit models to polychromatic or polytemporal data using NLOpt minimizers, to do Bayesian model selection via Nested sampling, and to bootstrap errors.
LITpro - Model Fitting Software
LITpro is model fitting software developed and maintained by JMMC. It can be used to model interferometric data written in the OIFITS format. The software provides a set of geometric and limb-darkening functions that can fit to visibilities, squared visibilities, and triple products. It provides plots to visualize the data, models, and results of the fits. Tools have been developed to help users find the global minimum.
CANDID - Companion Analysis and Non-Detection in Interferometric Data
The CANDID software is a suite of Python2.7 tools to detect faint binary companions in interferometric data in the OIFITS format. The software was developed by Antoine Mérand and Alexandre Gallenne. CANDID allows users to systematically search for faint companions, and if not found, to estimate the detection limit.
Binary Grid Search Procedure in IDL
This is a set of IDL routines to perform an adaptive grid search for binary stars. The code was written by Gail Schaefer. The program fits a binary model to interferometric data by searching through a grid of binary positions. It optimizes the solution at each step in the grid to find the global solution with the minimum chi squared.
SIMTOI - SImulation and Modeling Tool for Optical Interferometry
SIMTOI is a general-purpose model fitting program for optical interferometry developed by Brian Kloppenborg. It is designed to model complex astrophysical sources whose analytic Fourier transform is not easily computed. SIMTOI leverages the Open Graphics Language (OpenGL) and the Open Compute Language (OpenCL) to convert and compare its 3D, time- and wavelength-dependent models with several different types of data. SIMTOI can be used for simulation, visualization, minimization, and model selection problems.
Visibility Modeling Tool (VMT)
The VMT software application was developed by the NASA Exoplanet Science Institute (NExScI) to allow prospective or experienced users of optical interferometers to model the interferometric observables for objects of interest using a simple interface.
