DESI Y1 P1D related scripts and version control.

Installation

Install directly from GitHub:

pip install desi_y1_p1d@git+ssh://[email protected]/p-slash/desi-y1-p1d.git

• To install a specific version, add for example @v0.1 at the end.
• This will automatically install qsotools, qsonic and their requirements which include numpy, scipy, mpi4py, iminuit, .... However, it could be better if you setup your own environment first. Pay specific attention to mpi4py package that qsonic needs. Follow these instructions for NERSC.
• You are responsible for the DESI environment, which should not be a problem on NERSC.

Usage for mocks

setup-ohio-chain program is responsible for creating job scripts and chain scheduling them on NERSC Perlmutter. To streamline and version control the pipeline, certain settings are set within the package. Intended usage is to specify which settings to use. See avaliable settings in this folder or list them:

setup-ohio-chain --list-available-settings

You also need to set the following options:

• --root-dir: directory to save the mock spectra. It will create the correct folder structure within this.
• --delta-dir: directory to save the delta reductions. It will again create the correct folder structure.
• --rn1: starting value for the realization. default: 0
• --nrealizations: number of realizations. default: 1

Example: Create scripts for 10 Iron v0 realizations without any systematics and queue them.

setup-ohio-chain y1_iron_v0_nosyst --root-dir $PSCRATCH/ohio-mocks --delta-dir $PSCRATCH/ohio-deltas --nrealizations 10 --batch

You can change any option by providing a value in argument. However, you should also provide suffix(es) to distinguish these runs. To see the help and all options you can change:

setup-ohio-chain -h

To look into the details of your settings without running anything:

setup-ohio-chain [SETTING] --print-current-settings [other options can be passed.]

Finally, you can skip creating and batching scripts for transmissions files and/or quickquasars using --no-transmissions and --skip-qq options.

Usage for data

setup-desi-chain program is responsible for running Lya, SB1-2-3 analysis back to back. Its usage is similar to the mocks.
