CORRELATION REQUESTS (Defaults in parentheses): Correlator (Required if recording): JIVE Correlator average time (2 sec): 2.000 sec. Alternate average time (for spacecraft). 0.000 sec. Output spectral channels per baseband (16): 32 Correlator FFT size (128): 128 Number of antennas to be correlated: 12 Polarization (ON): ON Correlator weighting function (UNIFORM): UNIFORM Distribution tape (DAT): DAT Distribution format (FITS): FITS Source positions from: FROM SCHEDULE Shipping address for correlator output: An Institute A Street A Country Correlator Notes: --- DERIVED INFORMATION FOR CORRELATION: All scans Elapsed time for project (hours): 2.00 Total time in scheduled scans (hours): 1.83 Total time in recording scans (hours): 1.83 Total baseline hours (recording scans): 119.26 Projected max correlator output rate (kB/s): 319.5 Projected correlator output data size (MB): 1758.6 NOTES: Above numbers assume the same correlator parameters are used for all data. The 'baseline hours' include the autocorrelations (for data size calculations). The correlator output data rate is for real-time processing. Above numbers assume the same correlator parameters are used for all data. The recordings for a scan are assumed to start at the scan START minus PRESTART. Some stations (VLA, VLBA/MARK5C) wait for good data so the estimates may be high.

Notes on the station scan summaries: "Record Scans" are periods of recording with no gap. The Mark5A disk systems have a limit of 1024 such scans. There are often multiple projects on a disk pack. If using MARK5A, try to keep above about 6 GB per record scan by using MINPAUSE and PRESTART to prevent short gaps. However, also try to prevent record scans of more than an hour to minimize risk to data from playback problems. MARK5C will have one observe scan per record scan and there is no limit to the number.

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) NGC4151 84.2 J1209+4119 83.2 3C286 102.9 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.
