USNO Analysis Report for R11005 ($21JUN28XA) This report is a contributed analysis report that does not correspond to the database maintained by the IVS Data Centers for this session. (Analyzed by Christopher Dieck, US Naval Observatory. Spoolfile source: interactive nuSolve analysis.) Problems: NYALES20 - Station reports problems with the maser, which has an extreme clock rate. The extremeness and non-linearity of the clock rate meant that the data was unsuitable for session analysis. The station was deselected. RAEGSMAR - Cablecal was disconnected during the session. X-band LO tuner power problem, resulting in missed scans between scans 179-1821b and 180-1014. SEJONG - Suffered a data server error, resulting in missed scans between scans 180-0357b and 180-0649. WETTZELL - There was a lightning strike in the area of the observatory which disrupted observations from 180-00:16 -- 180-02:20. The cable cal was affected, and was not applied in session editing. Additionally, the disruption required the addition of a clock break. YEBES40M - Did not participate. Parameterization comments: - Atmospheric constraints on NYALE13S were elevated to 100 ps/hr. - Clock breaks were added as follows: WETTZELL 2021/06/29 01:18 - Baseline clocks offsets were applied on the following baselines: AGGO :NOTO HART15M :NOTO NOTO :ONSALA60 NOTO :RAEGSMAR NYALE13S:RAEGSMAR SEJONG :ONSALA60 SEJONG :SESHAN25 SEJONG :WETTZELL Other comments: - NYALE13S tagged along. - Due to dropped channels, the S-band ambiguity spacing is 50 ns on all SEJONG baselines. ----------------------------------------- Session Statistics Observations: 11857 scheduled 9132 correlated (in database) 5347 recoverable (usable) 5249 used Session fit: 49.012 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used AGGO 1077 603 594 55.2% HART15M 1387 784 772 55.7% HOBART26 684 523 518 75.7% KOKEE 1439 967 955 66.4% NOTO 2450 1450 1415 57.8% NYALE13S 1702 900 893 52.5% NYALES20 2550 0 NOT USED 0.0% ONSALA60 2506 1463 1434 57.2% RAEGSMAR 1658 414 407 24.5% SEJONG 1356 827 816 60.2% SESHAN25 1961 1332 1316 67.1% WETTZELL 2523 1431 1378 54.6% YEBES40M 2421 MISSED MISSED 0.0% --------------- --------- ----------- --------- ------ Station Total** 11857 5347 5249 44.3% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
