USNO Analysis Report for Q20312 ($20NOV07XK) 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: There was some noise in WETTZELL channels XR3U and XR4U, resulting in the SNR of XR3U and XR4U being only about 60% of XR1U. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 1 observation 24, WETTZELL:MK-VLBA , 0955+476, 10:27:42, quality codes - S:0, X:0 Number of observations rejected during analysis: 0 Other comments: None.
