IVS Analysis Report for RV138 ($19NOV25XB) 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: NYALES20 was noisy and has a low data yield. The VLBA correlator reported 'NY had clock rate that was both high and varied by channel'. They reported some ice on the dish and stopped for ~20 minutes for a rocket launch. There is a period of ~9 hours where most of the observations have zero codes (non-detections). The correlator reported low playback rates for NL-VLBA, around .5 in X-band, due to an RDBE2 problem. However, NL looks okay in the analysis. Parameterization comments: None. Other comments: Used 16 MHz channels at all stations, 4 X-band and 4 S-band channels, 2-bit sampling, 512 Mbit/sec. Some refringing was done to correct X-band subambiguities at NYALES20 and S-band subambiguites at BR-VLBA. ----------------------------------------- Session Statistics Observations: 19787 scheduled 18790 correlated (in database) 16532 recoverable (usable) 16200 used Session fit: 22.107 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used BR-VLBA 3427 2729 2677 78.1% FD-VLBA 3820 3350 3320 86.9% HARTRAO 867 745 721 83.2% HN-VLBA 3044 2770 2741 90.0% KP-VLBA 3825 3385 3352 87.6% LA-VLBA 3872 3458 3410 88.1% MK-VLBA 2732 2122 2102 76.9% NL-VLBA 3474 2849 2818 81.1% NYALES20 1724 836 593 34.4% ONSALA60 1085 912 874 80.6% OV-VLBA 3536 3058 3037 85.9% PIETOWN 3903 3126 3089 79.1% SC-VLBA 2928 2562 2539 86.7% WETTZELL 1337 1162 1127 84.3% --------------- --------- ----------- --------- ------ Station Total** 19787 16532 16200 81.9% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
