COVER INFORMATION Station: GBT_VLBA (Code Gb ) Experiment: NGC 6323 H2O Maser Exp. Code: BB242H Schedule Version: 1.00 Processed by SCHED version: 6.05 June 2006 PI: James A. Braatz Address: NRAO/CV Phone: 434-296-0251 EMAIL: jbraatz@nrao.edu Fax: Phone during observation: 434-296-0251 Observing mode: 512 Mb/s 1.3 cm Notes: GB pointing every roughly 60 minutes (10m). During 3 blocks of atmospheric cal, no GB pointing. Schedule for GBT_VLBA (Code Gb ) Page 2 NGC 6323 H2O Maser UP: D => Below limits; H => Below horizon mask. blank => Up. Early: Seconds between end of slew and start. Dwell: On source seconds. Tapes: Drive, Index, Start footage / Direction, Head Group, End footage. For disks, the footages are really the GBytes TPStart: Tape motion start time. Frequencies are LO sum (band edge). SYNC: Time correlator is expected to sync up. Automatic tape allocation specified. 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 ---------------------------------------------------------------------------------------- --- Sat 19 Apr 2008 Day 110 --- Next scan frequencies: 21981.49 21970.49 21936.49 21880.49 21813.49 21735.49 21623.49 21600.49 Next BBC frequencies: 981.49 970.49 936.49 880.49 813.49 735.49 623.49 600.49 Next scan bandwidths: 16.00 16.00 16.00 16.00 16.00 16.00 16.00 16.00 02 30 00 0825+030 11 00 55 40.1 234.7 2.6 39.8 0 1 1 0 02 30 00 02 31 00 --- 11 01 55 40.0 234.9 2.6 39.9 60 F 1 4 02 30 18 02 32 22 0854+200 11 03 17 56.9 245.6 2.1 49.4 0 1 1 4 02 31 00 02 33 22 --- 11 04 17 56.7 245.8 2.1 49.5 60 F 1 13 02 31 00 02 35 43 0958+472 11 06 39 74.8 311.4 1.1 119.8 0 1 1 13 02 33 22 02 36 43 --- 11 07 39 74.6 311.1 1.1 119.3 60 F 1 26 02 33 22 02 38 12 0958+653 11 09 08 61.1 345.1 1.2 151.0 0 1 1 26 02 36 43 02 39 12 --- 11 10 08 61.0 345.0 1.2 150.6 60 F 1 36 02 36 43 02 40 24 1058+811 11 11 21 47.2 359.3 0.2 176.5 0 1 1 36 02 39 12 02 41 24 --- 11 12 21 47.2 359.3 0.2 176.2 60 F 1 44 02 39 12 02 44 31 1146+395 11 15 28 83.6 433.9 -0.5 -101.0 31 1 1 44 02 44 31 02 45 31 --- 11 16 29 83.8 433.6 -0.5 -101.5 60 F 1 48 02 44 49 02 47 57 1357+764 11 18 54 48.0 372.7 -2.7 -131.4 0 1 1 48 02 45 31 02 48 57 --- 11 19 54 48.1 372.7 -2.6 -131.7 60 F 1 61 02 45 31 02 50 49 1640+394 11 21 48 30.3 421.2 -5.3 -63.2 0 1 1 61 02 48 57 02 51 49 --- 11 22 48 30.5 421.3 -5.3 -63.3 60 F 1 72 02 48 57 02 52 51 1740+521 11 23 50 27.1 403.4 -6.3 -61.3 0 1 1 72 02 51 49 02 53 51 --- 11 24 50 27.2 403.5 -6.3 -61.5 60 F 1 80 02 51 49 02 54 41 1746+622 11 25 40 31.2 392.6 -6.3 -65.8 0 1 1 80 02 53 51 02 55 41 --- 11 26 40 31.3 392.7 -6.3 -66.0 60 F 1 87 02 53 51 02 57 28 0102+582 11 28 28 8.9 347.7 10.4 18.6 0 1 1 87 02 55 41 02 58 28 --- 11 29 28 8.8 347.8 10.4 18.4 60 F 1 98 02 55 41 02 59 51 0217+734 11 30 50 25.8 348.1 9.2 35.5 0 1 1 98 02 58 28 03 00 51 --- 11 31 51 25.7 348.2 9.2 35.3 60 F 1 107 02 58 28 Schedule for GBT_VLBA (Code Gb ) Page 3 NGC 6323 H2O Maser UP: D => Below limits; H => Below horizon mask. blank => Up.
