*** WORK IN PROGRESS *** Pipeline for performing Fourier-space galaxy clustering analyses using Data Release 3 (DR3) from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP).

Stages

Available steps of the pipeline currently include:

• Acquisition of data from the HSC archive [get_data.py]
• Splitting of metadata into the different HSC fields (and optionally by photometric filter) [split_metadata.py]
• Cleaning of the raw catalogues [clean_catalogues.py]
• Making maps of various quantities from the survey metadata using decasu [make_maps_from_metadata.py]
• Create maps of the survey footprint, depth, and mask, along with maps of dust attenuation in each band and star counts, using information from the galaxy catalogues. [make_maps_from_catalogue.py]
• Create maps of the galaxy number counts and density contrast [make_galaxy_maps.py]
• Combine the maps from the individual HSC fields [combine_fields.py]
• Perform principal component analysis (PCA) on the systematics maps produced in previous stages [pca_systematics]
• Compute theoretical predictions for the clustering angular power spectra using CCL [theory_predictions.py]
• Compute the clustering angular power from the data using NaMaster [compute_power_spectra.py]
• Consolidate the angular power spectra information into Sacc files [make_sacc_files.py]
• Plot the angular power spectra [plot_power_spectra.py]
• Convert products from this pipeline into appropriate formats for TXPipe

Configuration

Each stage of the pipeline has a corresponding class in config.py, wherein one can find and modify the settings for that stage. Global settings for the pipeline can be found in the cf_global class, which is located near the top of the file. All other configuration classes inherit settings from cf_global.

Running locally

If running on a local machine, users can choose which stages to run by toggling the True/False settings located in MASTER.py.

Running on NERSC

If running on NERSC, users must instead choose which stages to run by commenting/uncommenting the appropriate stages in MASTER_NERSC.sh. Executing this script will then run the appropriate job script from the slurm_scripts directory.
