v1.2

This version of the code contains all the features that were used in Schreiber et al. (2018). The list below gives the full list of changes.

Features:

  • Added the APPLY_VDISP opion, to convolve SEDs with a fixed velocity dispersion.
  • Added the REST_MAG option to produce rest-frame magnitudes.
  • Added the CUSTOM_SFH_LOOKBACK option to have time running backwards in the custom SFH expression
  • Added the CONTINUUM_INDICES option to produce absorption line EWs, Dn4000, etc.
  • Added fast++-grid2fits tool to convert .grid files into .fits files.
  • Added fast++-sfh2sed tool to produce SED for a given SFH.
  • Added 'nmodel' as a possible output column, showing the number of models fit to each galaxy.
  • Added the NO_IGM option to disable IGM absorption.
  • Added the SFH_QUANTITIES option to output non-parametric quantities of the SFH.
  • When not using EAzY photometric redshifts, confidence intervals can now be freely chosen.
  • Added option to fit log(LIR) instead of LIR, better for galaxies with uncertain Tdust.
  • Added the INTERVAL_FROM_CHI2 option to compute conf intervals from chi2 grid directly.

Bug fixes:

  • Made sure that attenuation law never goes negative.
  • Added explicit check for galaxies with no valid data.
  • Added the DEBUG option to help identify invalid models.
  • Added explicit check to catch incorrect wavelength units in filters.
  • Fixed crash for galaxies with spectra but no valid photometry (thanks to Hugh Dickinson).
  • Fixed issues with unexpected line endings in input files.
  • Fixed bug where it was not possible to use the 'mw' dust law (thanks brojonat).
  • Fixed incorrect MC outputs for unsorted grids (e.g., metallicity, thanks Themiya Nanayakkara).
  • Fixed missing column names on the .input_res.fit files (thanks Themiya Nanayakkara).
  • Fixed MC conf intervals for gridded values close to grid edges (thanks Francesco Valentino).

Performances:

  • Added the 'generators' parallel execution scheme, which should be faster in all cases.
  • Improved performances of dust attenuation.
  • Faster implementation of the fit progress bar.
  • Improved speed of MAKE_SEDS by about a factor 5, and also enabled multithreading for this stage.
  • Simplified IGM absorption formula.
