README.md

This repository contains a set of tools to prepare PARSEC model files for UniDAM.

Model file is prepared in two steps:

1. python download.py {params}
2. python prepare_models.py BAND output_file

usage: download.py [-h] [-o OUTPUT] -b BAND [-a AGE] [-e EXTINCTION] [-f FEH]
                   [--all] [--single-feh]

    Tool to download PARSEC models.
    

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        Output file name
  -b BAND, --band BAND  Catalog to work with
  -a AGE, --age AGE     Age to wotk with
  -e EXTINCTION, --extinction EXTINCTION
                        Extinction (A_V) to wotk with
  -f FEH, --feh FEH     Metallicity to wotk with
  --all                 Download all metallicities/ages
  --single-feh          Download all ages for one metallicity

Example:

~>python download.py -b 2MASS -o 2MASS --all
~>python prepare_models.py 2MASS PARSEC.fits

File constants.py contains a dict of available BAND values. Default CMD version is 1.2S + COLIBRI PR16. Values with _old suffix are for the version 1.2S.

Requirements:

• numpy
• scipy
• astropy
• requests
• requests_toolbelt
• argparse
