Epoch 1: bc123m Observe date : 2002AUG05/217 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 100 mas from phase center self-cal passes 78% of the solutions. In Beam calibrator 2 also clearly detected at approx 95 mas 90% solutions passed both point sources, but analysis wrt eachother seems to indicate that inbeam 2 has hidden structure. pulsar image becomes double when imaged with inbeam 2. Also the pulsar is clearly detected at approx 80 mas. -------------------------- 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.
