It is well known that the polarization response varies across a field of view and while this can be ignored to first order (especially for small fields of view) for high dynamic range imaging and high spectral purity imaging this must be pro… text/html 2009-07-24T09:37:18+01:00 http://old.radionet-eu.org/fp7wiki/doku.php?id=jra:albius:documents:reports:eso_1st_report&rev=1248421038&do=diff Q2 Report ALBiUS.

The default plan is that the work will proceed in three phases: 1. Evaluate global fringe fitting algorithms (TBD), target date 1 January 2010. 2. Implement version of fringe fitting task within CASA sufficient for EVLA/ALMA commissioning and related activities (NRAO), target date 1 July 2010. 3. Implement VLBI/eMerlin CASA fringe fitting task by augm…
