The session uses a setup with 512 Mbps a The two ftp fringe-test scans, ftp-segments start at: (1) 16:09:58 UT (in scan 2, 2 sec) (2) 16:48:48 UT (in scan 7, 2 sec) The UT range for F14P1 was at a time the sun was more or less right over Arecibo, so all possible sources were close to the sun, and if we went down in Decl too much or used a too-low RA, then the elevations from Wb got under 10deg. The source used is a compromise on both counts (16.9deg from sun; Elev Wb >=20), while maintaining a compact-like Amp(|uv|) plot (at S-band). bob 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: 7 Polarization (ON): ON Correlator weighting function (UNIFORM): UNIFORM Distribution tape (DAT): NONE Distribution format (FITS): FITS Source positions from: STANDARD Shipping address for correlator output: Ivan Agudo Correlator Notes: DERIVED INFORMATION FOR CORRELATION: All scans Elapsed time for project (hours): 1.00 Total time in scheduled scans (hours): 0.89 Total time in recording scans (hours): 0.89 Total baseline hours (recording scans): 5.35 Projected max correlator output rate (kB/s): 6.1 Projected correlator output data size (MB): 19.7 NOTES: Above numbers assume the same correlator parameters are used for all data. 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.
