IVS Analysis Report for CN1888 ($19APR01XB) 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.) Problems: NL-VLBA cable cal has two breaks; was not applied. LA-VLBA missed the first 3 hrs due to recording problems. Channel S4 was deleted at BR, KP, NL and SC due to RFI. Parameterization comments: None. Other comments: The session started with the wrong code. There is a gap ~18:00 when the code was changed. The PIETOWN X-band receiver was somewhat warm but the data looks okay. LA-VLBA and MK-VLBA missed ~90 minutes for the daily UT1 Intensive. ----------------------------------------- Session Statistics Observations: 30933 scheduled 28796 correlated (in database) 27595 recoverable (usable) 27431 used Session fit: 24.951 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used BR-VLBA 6154 5313 5289 85.9% FD-VLBA 6616 6101 6066 91.7% HN-VLBA 6568 5976 5959 90.7% KP-VLBA 6470 5845 5802 89.7% LA-VLBA 6643 5244 5175 77.9% MK-VLBA 4262 3729 3720 87.3% NL-VLBA 6576 5986 5962 90.7% OV-VLBA 6044 5600 5576 92.3% PIETOWN 6630 6027 5968 90.0% SC-VLBA 5903 5369 5345 90.5% --------------- --------- ----------- --------- ------ Station Total** 30933 27595 27431 88.7% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
