NASA Analysis Report for Q20250 ($20SEP06XK)
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 Karen Baver, Goddard Space Flight Center VLBI Analysis Center.
Spoolfile source: interactive solve/nuSolve analysis.)
Problems: None.
Number of observations rejected during correlation: 0
Number of observations not usable by the software: 3
observation 7, WETTZELL:MK-VLBA , 1418+546, 07:39:16, quality code X: 9 S: 0, fringe code X: ' ' S: ' '
observation 18, WETTZELL:MK-VLBA , 0215+015, 08:00:56, quality code X: 0 S: 0, fringe code X: ' ' S: ' '
observation 19, WETTZELL:MK-VLBA , 0235+164, 08:02:12, quality code X: 0 S: 0, fringe code X: ' ' S: ' '
Number of observations rejected during analysis: 3
observation 1, WETTZELL:MK-VLBA , 1849+670, 07:30:20, which fits at 112.4 +/- 25.9 ps
observation 12, WETTZELL:MK-VLBA , 1800+440, 07:48:09, which fits at 101.4 +/- 33.0 ps
observation 17, WETTZELL:MK-VLBA , 2356+385, 07:57:26, which fits at 94.3 +/- 26.5 ps
Other comments: Due to the recent problems with the WETTZELL cable cal values, it is being noted
that the cable calibration correction was used for this session.
The WETTZELL cable cal values ranged from ~ -8 to ~ 12 ps.
Parameterization:
6 parameters:
UT1 offset
atmosphere offset for:
MK-VLBA WETTZELL
clock offset, first order term, and second order term for:
WETTZELL
