Using Perl in basic science and calibration pipelines for Spitzer Infrared Array Camera data


Object oriented Perl language pipelines generate calibration products and basic calibrated data from raw images taken by the Infrared Array Camera (IRAC) onboard NASA's Spitzer Space Telescope. The pipelines gather input data and control files, initiate database interactions, and manage data flow through C, C++, and Fortran component programs. The compiled component programs perform instrumental signature correction, calibration, and data characterization. Core pipeline functionality is provided by two compact Perl object hierarchies - one for pipelines and another for images. The objects allowed flexible and agile response to change during Spitzer's first year of operations, which offset the costimpact of utilizing interpreted Perl on production data processing.
