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

• 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.
  >> See more

• Line Profile Indicators
  This package 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.
  >> See more

• 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.
  >> See more

• MCAL
  A [Fe/H] and Teff calibrator for M dwarfs
  >> See more

• ODUSSEAS (Observing Dwarfs Using Stellar Spectroscopic Energy-Absorption Shapes)
  A Machine-Learning Tool for the derivation of Teff and [Fe/H] of M Dwarf stars
  >> See more

• RemoveYoung
  A tool for the removal of the young stellar component in galaxies within an adjustable age cutoff
  >> See more

• SOAP
  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.
  >> See more

• SOAP-T
  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.
  >> See more

• 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.
  >> See more

• TMCalc
  This simple 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).
