v1.5.1 (09/03/2023)
======
Bug fixes:
- Fixed index out of bounds when convolving for velocity dispertion
- Fixed possible race condition when saving all SEDS in a grid (pre-gridded SEDs only)
v1.5.0 (06/12/2023)
======
Features:
- Added option OUTPUT_PRECISION to control the numerical precision in the output catalog
v1.4.0 (11/08/2023)
======
Features:
- Added option TEMP_ERR_SPEC_FILE to control the template error function for the spectrum
- The spectrum no longer inherits the same template error function as the photometry
- AUTO_SCALE=1 no longer automatically disables the template error for the spectrum
- Added option SPEC_LSF_FILE to apply a line spread function to the models
- Added option LSF_BEST_FIT for appending the LSF-convolved model to the best fit output
Bug fixes:
- Fixed crash when saving extra outputs and using an absolute path in CATALOG
- Fixed invalid cache and grid files if using extremely large number of models or galaxies
v1.3.2 (16/07/2022)
======
Bug fixes:
- Fixed compilation with GCC 11.x
v1.3.1 (04/06/2021)
======
Features:
- Added line number information to error messages from the LIR input catalog
Bug fixes:
- Added missing "log_bc_age_max" to the hash for cached grids (will invalidate existing grids)
- Fixed grid2fits reading data in wrong order where there is more than one galaxy
- Fixed compilation with XCode 12
- Fixed compiler setup not properly propagated to dependencies (CFITSIO etc.)
v1.3.0 (12/06/2019)
======
Features:
- Added a differential attenuation model a la Charlot & Fall.
v1.2.1 (20/03/2019)
======
Bug fixes:
- Fixed best-fit SED wrong normalization when BEST_FROM_SIM=1 (thanks Themiya Nanayakkara)
- Fixed Milky Way attenuation curve (thanks anhackastro)
v1.2 (13/01/2019)
====
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.
v1.1 (08/11/2017)
====
Bug fixes:
- BEST_FROM_SIM=1 now produces valid chi2 and best-fit SEDs.
- The FILTER.RES file is now read exactly as in FAST and EAzY, to avoid some incompatibilities.
Other changes:
- When MAKE_SED=1, the fitting stage is now disabled and the program only creates the SEDs.
v1.0 (13/09/2017)
====
Features:
- This is the first release that contains all the features of the original FAST.
- Additional features:
- Custom star formation histories
- Priors on L_IR
- More outputs: average SFR, ionizing luminosity, dust luminosity, formed stellar mass, ...
- Create SEDs from list of models and stellar masses
- Multithreading
