pfstarget

This package contains scripts for the PFS Cosmology Survey target selection.

Installation

git clone https://github.com/pfs-cosmo/pfstarget.git
cd pfstarget
pip install -e . 

getting started

1. Download tracts from HSC using the script in bin/hsc/sql. You will need a STARS account for this. This is the imaging catalog that will be used for target selection.

python3 hscReleaseQuery.py s23b_wide_pfs.sql -D --user username -r s23

2. Apply target selection. You can do this in python by manually in python loading the tracts.

from astropy.table import Table
from pfstarget import cuts as Cuts

tract = Table.read('your_tract_file_name.fits') 

is_pfs_cosmo = Cuts.isCosmology(tract)

targets = tract[is_pfs_cosmo]

Or, you can use the scripts in bin/.

# select targets using DESI galactic extinction model 
python bin/select_targets.py DIR_WITH_TRACTS DIR_OUTPUT --dust desi  

# select targets using SFD98 galactic extinction model 
python bin/select_targets.py DIR_WITH_TRACTS DIR_OUTPUT --dust sfd98
