IVS Analysis Report for AUA020 ($17MAY01XA) 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, NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Note: This is the refringed version. Problems: A clock break is used at Hobart26 at 06:05 UTC due to an abrupt clock rate change. Parameterization comments: None. Other comments: Two sources observed very close to the sun: 0229+131 (~2.0 degrees away) and 0235+164 (~1.6 degrees away). Both show large offsets in X and S bands due to the solar corona. These are mostly corrected by the standard X/S ionosphere correction. However, a few points on the HH-ZC and HH-SV baselines are not adequately corrected. Many of the 0229+131 and 0235+164 points are lower quality codes (5-7). Two radio stars also observed: HR5907 and HD146361. HD146361 is not detected in either band. HR5907 gets 12 X-only detections, 5 S-only detections and 3 X/S detections. ----------------------------------------- Session Statistics Observations: 5218 scheduled 4703 correlated (in database) 4130 recoverable (usable) 4010 used Session fit: 30.974 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used BADARY 1674 1491 1460 87.2% HARTRAO 1273 1023 980 77.0% HOBART26 976 798 788 80.7% SEJONG 1773 1322 1304 73.5% SESHAN25 1714 1389 1330 77.6% SVETLOE 1465 1127 1099 75.0% ZELENCHK 1561 1110 1059 67.8% --------------- --------- ----------- --------- ------ Station Total** 5218 4130 4010 76.8% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
