Epoch 1: bc120g Observe date : 2003FEB09/040 Reduction date : 2003 Mar 25 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 this time self-cal passes 65% of the solutions. In Beam calibrator 2 also clearly detected at approx 95 mas 78% solutions passed In-beam 2 unreliable Also the pulsar is clearly detected at approx 130 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.
