SUMMARY FILE FOR PROJECT: BM177A COVER INFORMATION: Experiment: SiO near GC Exp. Code: BM177A Schedule Version: 2.00 Processed by SCHED version: Release of 02 July 2002 PI: Makoto Miyoshi Address: VERA Project Office National Astronomical Observatory 2-21-1, Osawa, Mitaka, Tokyo 181-8588, JAPAN Phone: 81 422 34 3937 EMAIL: miyoshi@miz.nao.ac.jp Fax: 81 422 34 3635 Phone during observation: 81 422 34 3937 Observing mode: VLBA Notes: Totally 4 passes are need, 1 pass for each IF. Exact coordinate of Sgr A* for correlation, which is different from that of the antenna pointing. SOURCE=SGRA RA=17:45:40.0392 DEC=-29:00:28.151 EPOCH=J2000 No cover letter provided. CORRELATION REQUESTS (Defaults in parentheses): Correlator (Required if recording): SOCORRO Correlator average time (2 sec): 0.200 sec. Alternate average time (for spacecraft). 0.000 sec. Spectral channels per baseband (16): 128 Number of antennas to be correlated: 10 Polarization (ON): OFF Correlator weighting function (UNIFORM): UNIFORM Distribution tape (DAT): DAT Source positions from: NOT SPECIFIED. Shipping address for correlator output: Makoto Miyoshi VERA Project Office National Astronomical Observatory 2-21-1, Osawa, Mitaka, Tokyo 181-8588, JAPAN Correlator Notes: DERIVED INFORMATION FOR CORRELATION: Elapsed time for project: 7.94 hours. Total time in scheduled scans: 7.13 hours. Total time in recording scans: 7.13 hours. Total number of baseline hours: 324.01 (Recording scans only) Projected maximum data output rate from the correlator: 1126.4 kbytes/sec if processed in one pass. Projected correlator output data set size: 23888.8 Mbytes NOTE: Above numbers assume the same correlator parameters are used for all data. NOTE: Output data set size large. Consider requesting high density tapes. ******** WARNING: Projected correlator output data rate exceeds VLBA correlator limit of 500 kbytes per second. Higher rates may be ok.

The solar corona can cause unstable phases for sources too close to the Sun. 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) NRAO530 29.4 SGRA 24.8 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.
