Tape positions are just estimates. ---------------------------------------------------------------------------------------- Start UT Source Start / Stop Early Tapes TPStart Stop UT LST EL AZ HA UP ParA Dwell (see above) SYNC ---------------------------------------------------------------------------------------- --- Fri 22 Dec 2006 Day 356 --- 23 20 00 J1925+2106 22 13 00 51.1 261.3 2.8 61.1 -12 1 1 184 23 20 00 23 22 00 --- 22 15 01 50.7 261.7 2.8 61.2 108 F 1 186 23 20 00 23 22 00 J1925+2106 22 15 01 50.7 261.7 2.8 61.2 -4 1 1 186 23 22 00 23 25 00 --- 22 18 01 50.1 262.2 2.9 61.3 176 F 1 189 23 22 00 23 25 00 J1924+1540 22 18 01 47.0 255.4 2.9 56.1 -12 1 1 189 23 25 00 23 30 00 --- 22 23 02 46.0 256.4 3.0 56.5 288 F 1 194 23 25 00 23 30 00 J1925+2106 22 23 02 49.1 263.0 2.9 61.5 -12 1 1 194 23 30 00 23 32 00 --- 22 25 02 48.7 263.4 3.0 61.6 108 F 1 195 23 30 00 23 32 00 J1925+2106 22 25 02 48.7 263.4 3.0 61.6 -4 1 1 195 23 32 00 23 35 00 --- 22 28 03 48.0 263.9 3.0 61.7 176 F 1 198 23 32 00 23 35 00 J1924+1540 22 28 03 45.0 257.3 3.1 56.8 -12 1 1 198 23 35 00 23 40 00 --- 22 33 03 44.0 258.3 3.1 57.2 288 F 1 203 23 35 00 23 40 00 J1925+2106 22 33 03 47.0 264.7 3.1 61.9 -12 1 1 203 23 40 00 23 42 00 --- 22 35 04 46.6 265.0 3.1 61.9 108 F 1 205 23 40 00 23 42 00 J1925+2106 22 35 04 46.6 265.0 3.1 61.9 -4 1 1 205 23 42 00 23 45 00 --- 22 38 04 46.0 265.5 3.2 62.0 176 F 1 208 23 42 00 23 45 00 J1924+1540 22 38 04 43.0 259.2 3.2 57.4 -12 1 1 208 23 45 00 23 50 00 --- 22 43 05 42.0 260.0 3.3 57.7 288 F 1 213 23 45 00 23 50 00 J1925+2106 22 43 05 45.0 266.3 3.3 62.1 -12 1 1 213 23 50 00 23 52 00 --- 22 45 05 44.5 266.6 3.3 62.1 108 F 1 215 23 50 00 23 52 00 J1925+2106 22 45 05 44.5 266.6 3.3 62.1 -4 1 1 215 23 52 00 23 55 00 --- 22 48 06 43.9 267.1 3.4 62.2 176 F 1 218 23 52 00 23 55 00 J1924+1540 22 48 06 40.9 260.9 3.4 57.9 -12 1 1 218 23 55 00 23 59 59 --- 22 53 07 39.9 261.7 3.5 58.1 287 F 1 223 23 55 00 SETUP FILE INFORMATION: NOTE: If DOPPLER, FREQ, or BW were used, see the individual scans for the final BBC settings.

The solar corona can cause unstable phases for sources too close to the Sun. SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) J1924+1540 43.8 J1925+2106 48.8 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz. For common VLBI bands, this is: 327 MHz 117. deg 610 MHz 81. deg 1.6 GHz 45. deg 2.3 GHz 36. deg 5.0 GHz 23. deg 8.4 GHz 17. deg 15.0 GHz 12. deg 22.0 GHz 9. deg 43.0 GHz 6. deg
