IVS Analysis Report for RD1703 ($17FEB20XA) 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, Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: NYALES20: Was fringed with manual phase cals, reason not given. This is generally not a good idea for NYALES20, where the phase cal and cable cal often shows an elevation depencence. NY missed ~5-6 hrs due to high winds. There is a clock break between 10:07 and 10:43 UTC, corresponding to a formatter re-sync. Ambiguity resolution was difficult. Low data yield due to winds and probably lower SNR's due to snow. KUNMING: Noisy and has subambiguities. Clock break at ~18:10 UTC. Some of the KM baselines have large baseline clock offsets. HOBART26: Low yield, lots of zero codes. Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 1595 scheduled 1434 correlated (in database) 1011 recoverable (usable) 941 used Session fit: 28.390 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HARTRAO 327 189 159 48.6% HOBART26 197 62 54 27.4% KUNMING 437 212 151 34.6% MEDICINA 578 469 461 79.8% NYALES20 552 226 212 38.4% ONSALA60 510 394 385 75.5% WETTZELL 589 470 460 78.1% --------------- --------- ----------- --------- ------ Station Total** 1595 1011 941 59.0% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
