Software tools

This page contains a list of the public software tools developed by team members and relevant to the EXOEarths project.

A C++ based program to automatically measure line Equivalent widths in stellar Spectra.

>> ARoME
This library is designed to generate analytical Rossiter-McLaughlin effects.

A Python-based program to calculate the Bayesian Generalized Lomb-Scargle periodogram of time-series. More information can be found in Mortier et al. (2015).

Correlation Analysis in the Bayesian Framework. More information can be found in Figueira, P. et al. (2015).

>> GeTCal
The Great Tool for Calibration, GeTCal, computes the Teff and [Fe/H] calibrations, plots the fitting procedures and prints calibration files compatible with TMCalc. Can be used with any sample to obtain new calibrations. You can also find here updated calibration files that work for both FGK-dwarfs and GK-giants.

A package for the analysis of RV data, using the Diffusive Nested Sampling algorithm for posterior exploration and Gaussian processes as correlated noise models.

>> KS integration
A software that solves for mutual photometric effects produced by planets and spots allowing to analyze planetary occultations of spots and spots regions.
More information here.

>> Line Profile Indicators
Line Profile Indicators analysis package that evaluates automatically the indicators described in Figueira et al. (2013), assessing the statistical significance of the correlation between each of these indicators and the measured radial velocities.

>> LineSearcher
The LineSearcher code is based on the ARES code algorithms. You can use it to search all the absortion lines in a given wavelength interval. This code returns the center wavelength and estimated depth for each spectral line.

A [Fe/H] and Teff calibrator for M dwarfs.

SOAP is a free tool that simulates the effects of dark spots and bright plages on the surface of a rotating star, computing their expected radial velocity and photometric signatures.

SOAP is a free tool that can generate the radial velocity variations and light-curves for systems consisting of a rotating spotted star with a transiting planet.

>> TeffLR
This code (in C++), another extension of ARES, can be used to estimate the spectroscopic temperature for FGK dwarf stars using a line-ratio method.

>> TMCalc
This simple code TMCalc is a C code developed as an extension to ARES. Using the line list given it uses the calibration derived for several line-ratios to estimate the spectroscopic temperature for FGK dwarf stars and the use the iron lines strength calibration to derive the metallicity [Fe/H]. The calibration for the metallicity is described in a work (Sousa et al. 2012A&A, 544A, 122S).
