Epoch 1: bc123d Observe date : 2002JUN28/179 Reduction date : 2002 Sep 08 Using autoaips 0.9.9b on Parallax disk 7 -------------------------------- SUMMARY ---------------------------------- J2322+4445 (phase, bpass cal) -- an excellent calibrator. In-beam source is compact and bright enough Pulsar detected at about 10 mJy -- great image after in-beam calibration! Recommendations -- This pulsar has an excellent chance of being parallaxed. Observing strategy should stay the same, with the possible removal of J2349+3849 from the list of geodesy calibrators due to its structure. ---------------------------- DETAILS OF REDUCTION ------------------------- INBEAM 1 : ib_cal_name1 = B2310+42.14 ib_cal_ra1 = 23:12:13.49560 ib_cal_dec1 = 42:39:32.3585 ib_cal_s14001= 8.7 # mJy ib_cal_sep1 = 17.0 # arcmin 1.
