Final Correlator Notes B o n n C o r r e l a t o r [ Geodetic Institute of University of Bonn ] IRIS - S159 (No#1590) Earliest scan: 101-043-140000 Latest scan: 101-044-135100 Earliest procdate: 101-109-1311 Latest procdate: 101-109-1442 Stations present: AEFHJPV Baselines present: FE AV FV EV AE AJ JE JV FA JH AH HV FJ FH FP JP HP HE Frequencies present: SX Polarizations present: RR SNR extrema: 4.390 190.3 Exported: 26. April 2001 FQ summary spot 86% = FQ 6-9 4% = FQ 0,1-5,A-H 10% = FQ N,- STATIONS -------- FORTALEZA (Ft-F) > Occasionally shows lower amplitude in S-band "f" channel; GILCREEK (Gc-A) > normal HARTRAO (Hh-J) > Showed 20% to 40% lower amplitude in the channel "a" (freq. 2212.99) in S-band; HOBART (Ho-H) > S-band channel "f" (freq. 2322.99) had low amplitude for most of the scans (30% to 60%); O'HIGGINS (Oh-P) > It was the first observation with the new VLBA4 Data Acquisition Rack. There were problems with the wiring of some cables and the 1 PPS. The FS-PC installed by Ed Himwich in Wettzell was running, and the sources could be tracked. Despite of this there were still some modifications necessary. Phasecal was also a problem here for some scans is instable. A broken wire in the RF- way from the Antenna Unit to the X-Band coupler was found. Due to technical problems, Oh observed only between UT: 043/1740 - 2234 (18%). WESTFORD (Wf-E) > Significant lower amplitudes in S-band channel "f" (freq. 2322.99) in all baselines (30% to 70%); WETTZELL (Wz-V) > Problem with finding a proper start time for 9 scans, they were correlated without Wz station.

Several scans (15%) were re-correlated.
