Results from Oct 2008 AIPS (with Hobart mount). data path TABED – fix the AN table (use new versions of ATLOD) CLCOR – apply feed rotation corrections: CL#2 FRING – Find solutions: SN#4 SNCOR – Copy sols from POL 1 to POL 2 CLCAL – Apply: CL#3 FRING – Find delays for RR to LL: SN#5 SNCOR – Zero Rate and Phase CLCAL – Apply average delay: CL#4 CALIB – find phase difference: SN#6 CLCAL – Apply: CL#5
Repeat SN#4-6 to CL#1 to produce CL#6,7,8
The plot shows the difference in the phases between RR and LL for V187A (1& 2) and B (3&4), with (1&3) and without (2&4) corrections.
