UniPOPS: Unified data reduction suite

Abstract: UniPOPS, a suite of programs and utilities developed at the National Radio Astronomy Observatory (NRAO), reduced data from the observatory's single-dish telescopes: the Tucson 12-m, the Green Bank 140-ft, and archived data from the Green Bank 300-ft. The primary reduction programs, 'line' (for spectral-line reduction) and 'condar' (for continuum reduction), used the People-Oriented Parsing Service (POPS) as the command line interpreter. UniPOPS unified previous analysis packages and provided new capabilities; development of UniPOPS continued within the NRAO until 2004 when the 12-m was turned over to the Arizona Radio Observatory (ARO). The submitted code is version 3.5 from 2004, the last supported by the NRAO.

Additional information on this code:

UniPOPS was a suite of programs and utilities that were developed at the National Radio Astronomy Observatory (NRAO), first deployed in January 1991, and designed for reducing data from the observatory's single-dish telescopes -- the Tucson 12-m, the Green Bank 140-ft, and archived data from the Green Bank 300-ft. The primary reduction programs, 'line' (for spectral-line reduction) and 'condar' (for continuum reduction), used the People-Oriented Parsing Service (POPS) as the command line interpreter. POPS has had a 40-year history within the NRAO and elsewhere -- created in the 1970's by Jerry Hudson, subsequently adapted to single-dish analysis systems by Tom Cram, and related to the interpreter still used by AIPS. Before the start of the UniPOPS project, the 12-m and the Green Bank telescopes used what looked to the user like similar data reduction programs but were in fact very different at the code level. The "Uni" in UniPOPS signifies that this package meant to unify the previous analysis packages. Since the new system was meant to run on Sun workstations, a major upgrade from the computers previously used for data reduction, the capabilities of the software were also upgraded. For example, more memory was now available for adding new analysis routines; in comparison to its predecessors, the user-interface of UniPOPS incorporated many of the features one expected of software systems of its day, most significantly it took advantage of X-Windows. Development of UniPOPS continued within the NRAO until 2004 when the 12-m was turned over to the Arizona Radio Observatory (ARO). By then, the 140-ft had been decommissioned and the observatory had decided to use Aips++ as the analysis system for the recently-finished Green Bank Telescope. The submitted code is version 3.5 from 2004, the last supported by the NRAO. The ARO has since modified UniPOPS to run on Linux-based systems. (Bob Garwood)
