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.
