CORRELATION REQUESTS (Defaults in parentheses): Correlator (Required if recording): SOCORRO Correlator average time (2 sec): 1.000 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: SCHEDULE Shipping address for correlator output: Francisco Colomer Observatorio Astronomico Nacional Campus Universitario. Ctra N-II, km 33,6 E-28871 Alcala de Henares (SPAIN) Correlator Notes: Please use 256 spectral points per band and 1 second integration if possible DERIVED INFORMATION FOR CORRELATION: Elapsed time for project: 5.95 hours. Total time in scheduled scans: 5.48 hours. Total time in recording scans: 5.48 hours. Total number of baseline hours: 288.88 (Recording scans only) Projected maximum data output rate from the correlator: 450.6 kbytes/sec if processed in one pass. Projected correlator output data set size: 8519.3 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.
