Suitable for dynamic scheduling. VLBA 12h track centered at 12:30 LST (VLBA_PT). All VLBA stations requested. Track must start/stop w/ cal scan. No cover letter provided. CORRELATION REQUESTS (Defaults in parentheses): Correlator (Required if recording): SOCORRO Correlator average time (2 sec): 8.000 sec. Alternate average time (for spacecraft). 0.000 sec. Spectral channels per baseband (16): 256 Number of antennas to be correlated: 10 Polarization (ON): OFF Correlator weighting function (UNIFORM): UNIFORM Distribution tape (DAT): DAT Source positions from: VLBA DATABASE Shipping address for correlator output: Lincoln Greenhill Harvard-Smithsonian CfA, M.S. 42 60 Garden St Cambridge, MA 02138 Correlator Notes: DERIVED INFORMATION FOR CORRELATION: Elapsed time for project: 11.80 hours. Total time in scheduled scans: 10.27 hours. Total time in recording scans: 10.27 hours. Total number of baseline hours: 541.66 (Recording scans only) Projected maximum data output rate from the correlator: 225.3 kbytes/sec if processed in one pass. Projected correlator output data set size: 3993.5 Mbytes NOTE: Above numbers assume the same correlator parameters are used for all data.
