| Abstract: |
Traditional polarization calibration functionality in user-oriented
software packages for synthesis interferometry have tended to
hard-code for a specific range of assumptions about observing
properties and conditions (e.g. for the particular instrument they
principally support), most notably the polarization basis of the
receivers. This limits flexibility in supporting diverse instruments
and complicates the development of high-level pipelines which must
incorporate complicated logic to discern the appropriate heuristics to
apply. We here describe recent CASA polarization calibration
developments concerning cross-hand phase that endeavor to permit a
more basis-agnostic approach in automated processing. |
