Analysis of radial velocity and photometric datasets

  • archi
    An expansion to the CHEOPS official pipeline that can analyse background stars and produce photometric time-series of several close-by targets at once. Different stars in the image can also be used to calibrate systematic errors and contamination to the main target .

  • 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.

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

  •  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.

  •  Line Profile Indicators
    This package evaluates 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.

  •  SOAP
    SOAP is a 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-T
    SOAP-T is an extension of SOAP which can generate the radial velocity variations and light-curves for systems consisting of a rotating spotted star with a transiting planet.

  • FASMA – Fast Analysis of Spectra Made Automatically
    A tool to analyze stellar spectra and derive stellar parameters and abundances. Described in more detail in Andreasen et al. (2017) and Tsantaki et al. (2020).

  • GeTCal – The Great Tool for Calibration
    This tool computes the Teff and [Fe/H] calibrations, plots the fitting procedures and prints calibration files compatible with TMCalc.
    🔗 See more
  • LineSearcher
    The LineSearcher code is based on the algorithms from ARES. It can search all the absorption lines in a given wavelength interval. The code returns the center wavelength and estimated depth for each spectral line.

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

  • 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
  • TeffLR
    This C++ code was developed as an extension to ARES. It can be used to estimate the spectroscopic temperature for FGK dwarf stars using a line-ratio method.
    🔗 See more
  • TMCalc
    This C code was developed as an extension to ARES. Using a given line list, 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 Sousa et al. (2012).
