USNO Analysis Report for Q18043 ($18FEB12XK) 
       This report is a contributed analysis report that does not correspond to 
       the database maintained by the IVS Data Centers for this session.  
   (Analyzed by Christopher Dieck, US Naval Observatory.
    Spoolfile source: interactive nuSolve analysis.) 

Problems: The correlator reports that NYALES20 reports that they "observed with warm receiver due to power outage in the receiver box. Only a hand-full of 'useable' scans in X-band with very low SNR; S-band okay" and that SESHAN25 had "RFI in S-band, particularly strong in channel SR5U."

Number of observations rejected during correlation:    0 

Number of observations not usable by the software:    50 
      49 scans were not usuable due to the issues at NYALES20 identified in the station report.
      The other scan was:
        observation 18, ISHIOKA :WETTZELL, 0642+449, 07:02:39, quality code X-band: 0 S-band: 9

Number of observations rejected during analysis:      21
      The 21 scans of the WETTZ13N:WETTZELL baseline were deselected as is the practice of this analysis center. 

Other comments: None.
