""" This script defines the HST Advanced Products (HAP) generation portion of the
    calibration pipeline.  This portion of the pipeline produces mosaic and catalog
    products. This script provides similar functionality as compared to the Hubble
    Legacy Archive (HLA) pipeline in that it acts as the controller for the overall
    sequence of processing.

    Note regarding logging...
    During instantiation of the log, the logging level is set to NOTSET which essentially
    means all message levels (debug, info, etc.) will be passed from the logger to
    the underlying handlers, and the handlers will dispatch all messages to the associated
    streams.  When the command line option of setting the logging level is invoked, the
    logger basically filters which messages are passed on to the handlers according the
    level chosen. The logger is acting as a gate on the messages which are allowed to be
    passed to the handlers.

    Creation of source catalogs can be controlled through the use of environment variables:


    These variables can be defined using values of:

      - 'on', 'true', 'yes' : Create catalogs
      - 'off', 'false', 'no' : Turn off generation of catalogs

    The output products can be evaluated to determine the quality of the alignment and
    output data through the use of the environment variable:

    - SVM_QUALITY_TESTING : Turn on quality assessment processing.  This environment
      variable, if found with an affirmative value, will turn on processing to generate a JSON
      file which contains the results of evaluating the quality of the generated products.

    NOTE: Step 9 compares the output HAP products to the Hubble Legacy Archive (HLA)
    products. In order for step 9 (run_sourcelist_comparison()) to run, the following
    environment variables need to be set:

    Alternatively, if the HLA classic path is unavailable, The comparison can be run using
    locally stored HLA classic files. The relevant HLA classic imagery and sourcelist files
    must be placed in a subdirectory of the current working directory called 'hla_classic'.
