Epoch 1: bc123as Observe date : 2002NOV15/319 Reduction date : 2003 Mar 24 Using autoaips 1.0.0 on Astrud disk 1 -------------------------------- SUMMARY ---------------------------------- Phase calibrator -- detected as an extended source with clear lobe structure In Beam calibrator 1: clearly detected at approx 105 mas from phase center self-cal passes 75% of the solutions. In Beam calibrator 2 also clearly detected at approx 95 mas 83% solutions passed Hidden structure in inbeam 2 makes motion unreliable. Also the pulsar is clearly detected at approx 115 mas. imaging with in-beam 2 solutions smears out the image somewhat -------------------------- DETAILS OF REDUCTION ----------------------- INBEAM 1 : ib_cal_name1 = B2045-16.11 ib_cal_ra1 = 20:48:36.69994 ib_cal_dec1 = -16:09:45.4394 ib_cal_s14001= 19.0 # mJy ib_cal_sep1 = 7.0 # arcmin 1.
