Codes used to create LSS catalogue and randoms
LSScatGen.py is a python code that creates the LSS catalogue for quicksurvey2016.
The random files are generated by a bunch of scripts.
bm_imaging.py looks at the input targeting file and models average number density as a function of various parameters (extinction, depth, etc.)
This information is then read by make_imaging_ran.py which makes random catalogues reflecting the angular variations in the targeting.
For sample .slurm and input/output files see /project/projectdirs/desi/datachallenge/LSScat on NERSC
For sample output catalogue and randoms see /project/projectdirs/desi/datachallenge/LSScat/quicksurvey2016 and /project/projectdirs/desi/datachallenge/LSScat/quicksurvey2017 on NERSC
To get the catalogue, randoms, and the correlation function/power spectra you can submit the following jobs in the following order to NERSC:
test_lsscat.slurm (creates LSS catalogue, can be run independently of others in any order)
test_bm_imaging.slurm (backwards modelling imaging randoms, has to be run before other random creating scripts)
test_imaging_ran.slurm (creating imaging randoms, has to be run after the “backwards modelling imaging” step)
