USNO Analysis Report for Q20244 ($20AUG31XK) 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: NYALSE20 did not participate. WETTZELL cable calibration spans a wide range of delays and significatly degraded the session fit. Thus, the correction was not applied. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 9 observation 19, SESHAN25:WETTZ13N, 1806+456, 07:08:38, quality codes - S:9, X:0 observation 20, SESHAN25:WETTZELL, 1806+456, 07:08:38, quality codes - S:9, X:0 observation 45, WETTZ13N:WETTZELL, 0814+425, 07:23:08, quality codes - S:4, X:9 observation 48, WETTZ13N:WETTZELL, 0738+491, 07:24:16, quality codes - S:4, X:9 observation 78, WETTZ13N:WETTZELL, 1039+811, 07:38:09, quality codes - S:2, X:9 observation 81, WETTZ13N:WETTZELL, 1053+704, 07:39:24, quality codes - S:3, X:9 observation 90, WETTZ13N:WETTZELL, 1324+224, 07:44:34, quality codes - S:4, X:9 observation 111, WETTZ13N:WETTZELL, 0827+243, 07:53:50, quality codes - S:4, X:6 observation 114, WETTZ13N:WETTZELL, OJ287 , 07:54:54, quality codes - S:3, X:9 Number of observations rejected during analysis: 12 observation 9, WETTZ13N:WETTZELL, 1039+811, 07:03:25, which fits at -699.3 +/- 15.9 ps observation 21, WETTZ13N:WETTZELL, 1806+456, 07:08:38, which fits at 25322.3 +/- 21.2 ps observation 27, WETTZ13N:WETTZELL, 1417+385, 07:11:57, which fits at 925.5 +/- 18.0 ps observation 36, WETTZ13N:WETTZELL, 0827+243, 07:19:37, which fits at -3310.9 +/- 17.1 ps observation 42, WETTZ13N:WETTZELL, 0805+410, 07:22:06, which fits at 385.3 +/- 16.4 ps observation 51, WETTZ13N:WETTZELL, 0613+570, 07:25:35, which fits at -2521.8 +/- 16.1 ps observation 63, WETTZ13N:WETTZELL, 2000+472, 07:32:15, which fits at -150.6 +/- 18.3 ps observation 69, WETTZ13N:WETTZELL, 1842+681, 07:34:36, which fits at -25712.9 +/- 20.1 ps observation 93, WETTZ13N:WETTZELL, 1156+295, 07:46:10, which fits at 3549.2 +/- 16.8 ps observation 96, WETTZ13N:WETTZELL, 1059+282, 07:47:33, which fits at 752.3 +/- 18.4 ps observation 99, WETTZ13N:WETTZELL, 1015+359, 07:48:45, which fits at 8502.6 +/- 18.9 ps observation 102, WETTZ13N:WETTZELL, 1030+415, 07:49:50, which fits at -183.9 +/- 17.4 ps Other comments: None.
