SUMMARY FILE FOR PROJECT: EX010B COVER INFORMATION: Experiment: Varstrometry selected dual-Quasar candidates Exp. Code: EX010B Start Day 146 is Sat 25 May 2024 MJD 60455 Schedule Version: 2.00 Processed by SCHED version: 11.60 Release 11.6; April 2020 PI: Wancheng Xu Address: Xinjiang Astronomical Observatory, CAS 150 Science-1 Street Urumqi China Phone: +8615141589572 EMAIL: xuwancheng@xao.ac.cn Fax: Phone during observation: +8615141589572 Observing mode: vlbi Notes: # Please, make sure PHASE CAL is OFF # COVER LETTER: The coordinates of calibrators are from Astrogeo Database (rfc_2023c). 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: 14 Polarization (ON): ON Correlator weighting function (UNIFORM): UNIFORM Distribution tape (DAT): DAT Distribution format (FITS): FITS Source positions from: STANDARD Shipping address for correlator output: N/A Correlator Notes: DERIVED INFORMATION FOR CORRELATION: All scans Elapsed time for project (hours): 5.00 Total time in scheduled scans (hours): 4.14 Total time in recording scans (hours): 4.14 Total baseline hours (recording scans): 422.47 Projected max correlator output rate (kB/s): 215.0 Projected correlator output data size (MB): 3114.8 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.

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.
