Quality Assurance

Overview

The desisim pacakge includes a few scripts for running QA on the outputs.

Scripts

desi_qa_zfind

Generate redshift accuracy QA based on the truth vs. RedRock outputs.

usage

Here is the usage:

usage: desi_qa_zfind [-h] [--verbose] [--load_simz_table LOAD_SIMZ_TABLE]
                     [--reduxdir PATH] [--rawdir PATH] [--yaml_file YAML_FILE]
                     [--qafig_path QAFIG_PATH]
                     [--write_simz_table WRITE_SIMZ_TABLE]

Generate QA on redshift for a production [v0.2.1]

optional arguments:
  -h, --help            show this help message and exit
  --verbose             Provide verbose reporting of progress. (default:
                        False)
  --load_simz_table LOAD_SIMZ_TABLE
                        Load an existing simz Table to remake figures
                        (default: None)
  --reduxdir PATH       Override default path ($DESI_SPECTRO_REDUX/$SPECPROD)
                        to processed data. (default: None)
  --rawdir PATH         Override default path ($DESI_SPECTRO_REDUX/$SPECPROD)
                        to processed data. (default: None)
  --yaml_file YAML_FILE
                        YAML file for debugging (primarily). (default: None)
  --qafig_path QAFIG_PATH
                        Path to where QA figure files are generated. Default
                        is specprod_dir+/QA (default: None)
  --write_simz_table WRITE_SIMZ_TABLE
                        Write simz to this filename (default: None)

example

Here is the typical execution:

desi_qa_zfind

desi_qa_s2n

Generate S/N QA for all object types for all of the nights in a production. The object types and redshifts are taken from truth.

usage

Here is the usage:

usage: desi_qa_s2n [-h] [--reduxdir PATH] [--qafig_path QAFIG_PATH]

Generate S/N QA for a production [v0.2.1]

optional arguments:
  -h, --help            show this help message and exit
  --reduxdir PATH       Override default path ($DESI_SPECTRO_REDUX) to
                        processed data. (default: None)
  --qafig_path QAFIG_PATH
                        Path to where QA figure files are generated. Default
                        is specprod_dir+/QA (default: None)

examples

Generate the figures:

desi_qa_s2n

A series of PNG files are created for the various cameras and object types.
