E. G., Dubois Y., Pichon C. and Laigle C., MNRAS, 474, 3140*### Contact:[g.martin4@herts.ac.uk](mailto:g.martin4@herts.ac.uk "email")### Purpose:Reads `fractions.dat` binary file and returns the joint progenitor probability for given redshift, mass, environment (percentile) and star-formation rate (i.e. the probability that a galaxy with given properties has spheroidal morphology at z=0). If one or more dimensions are not specified, the joint progenitor probability is returned with missing dimensions marginalised out.### Prerequisites:* `fractions.dat`* numpy* scipy### Installation: pip install progenitor-probability### Usage:#### Using the built-in script:```tabulate_progenitor_probability.py -z 0.4 -m 10.80.266751184855``` ``` tabulate_progenitor_probability.py --helpusage: tabulate_progenitor_probability.py [-h] [-z REDSHIFT] [-m MASS] [-p DENSITY] [-s SFR]optional arguments: -h, --help show this help message and exit -z REDSHIFT, --redshift REDSHIFT Redshift -m MASS, --mass MASS Log10 stellar mass/M_sun -p DENSITY, --density DENSITY Local number density percentile [0,100] -s SFR, --SFR SFR SFR in M_sun/yr``` **-z** *redshift***-m** *log₁₀(stellar mass / M_sun)***-p** *percentile of local number density* in the range [0,100] (see [Martin et al. 2018a](https://doi.org/10.1093/mnras/stx3057 "Martin+18a"))**-s** *star formation rate in M_sun/yr*#### Importing the package```from progenitor_probability import progenitor_probability>>> progenitor_probability(redshift=0.4, mass=10.8)0.266751184855```
