IVS Analysis Report for RV145 ($21JAN27XA) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by David Gordon, US Naval Observatory. Spoolfile source: interactive nuSolve analysis.) This is a new version. NYALE13S was refringed using manual phase cals NYALE13S is now much less noisy (52 vs 189 psec) than in the original version and ~50% more observations are uasable (1132 vs 760). The new version has been submitted to IVS. Problems: HOBART26: Very low data yield. The VLBA correlator reported: 'Some of the HO data was corrupted with bad scan headers. I think there were some number of additional scans that did not play back correctly during correlation.' The VLBA may try to recorrelate this session, in which case an updated database would be released. BR-VLBA: Snowing. HARTRAO: Low data yield. Many of their scans were with HOBART26. KP-VLBA: Did not observe, commercial power outage. LA-VLBA: X-band receiver problems, no usable data in the first 2 channels. The remaining two channels produce 8.33 nsec ambiguities. Manual phase cals used in X and S bands. NYALE13S: Was tagged along. Manual phase cals were used. OV-VLBA: Snow and high winds. SC-VLBA: Did not observe due to elevation gearbox damage. SESHAN25: Noisy; low X-band SNR's; most X-band obs are zero codes. Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 22719 scheduled 15164 correlated (in database) 12547 recoverable (usable) 12406 used Session fit: 25.467 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used BR-VLBA 3773 2450 2427 64.3% FD-VLBA 4105 2838 2815 68.6% HARTRAO 444 199 182 41.0% HN-VLBA 3455 2461 2445 70.8% HOBART26 495 102 100 20.2% KP-VLBA 4085 NOT CORR NOT CORR 0.0% LA-VLBA 4175 2952 2909 69.7% MK-VLBA 2806 1865 1838 65.5% NL-VLBA 3904 2713 2693 69.0% NYALE13S 1683 1151 1132 67.3% ONSALA60 2062 1535 1524 73.9% OV-VLBA 3834 2455 2429 63.4% PIETOWN 4194 2810 2790 66.5% SC-VLBA 3338 NOT CORR NOT CORR 0.0% SESHAN25 1169 151 125 10.7% WETTZELL 1916 1412 1403 73.2% --------------- --------- ----------- --------- ------ Station Total** 22719 12547 12406 54.6% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
