SUMMARY FILE FOR PROJECT: FR067 COVER INFORMATION: Experiment: Ur 4Gbps test Exp. Code: FR067 Start Day 79 is Thu 20 Mar 2025 MJD 60754 Schedule Version: 3.00 Processed by SCHED version: 11.60 Release 11.6; April 2020 PI: campbell Address: JIVE Phone: 0521-596-534 EMAIL: campbell@jive.eu Fax: Phone during observation: Observing mode: Notes: Ur,T6,O8 6cm 4Gbps stay on 0234+185, 4 ftp fringe-test transfers (40min apart) full correl later v2: shifted to 20mar 1330 UT; v3: Ur with 5C not 5B as rec_trans_type COVER LETTER: This is the schedule for a 6 cm fringe test on 20 March 2025 for Ur at 4Gbps, involving 3 antennas: On85 T6 Ur The schedule consists of 5-min scans of 0234+185 2-sec ftp-fringe segments are scheduled as follows: 13:38:00 (scan 2) 14:18:00 (scan 7) 14:58:00 (scan 12) 15:38:00 (scan 17) 16:18:00 (scan 22) thus every 40m, to allow more time for the larger transfers from Ur to arrive. Last transfer in the next-to-last scan. Mattermost: coms.evlbi.org 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): 16 Correlator FFT size (128): 128 Number of antennas to be correlated: 11 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: JIVE Correlator Notes: DERIVED INFORMATION FOR CORRELATION: All scans Elapsed time for project (hours): 3.00 Total time in scheduled scans (hours): 1.87 Total time in recording scans (hours): 1.87 Total baseline hours (recording scans): 11.20 Projected max correlator output rate (kB/s): 24.6 Projected correlator output data size (MB): 165.2 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.

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) 4C39.25 127.7 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.
