NASA Analysis Report for Q21108 ($21APR18XK)
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: 4
observation 2, WETTZELL:MK-VLBA , 1746+470, 07:32:17, quality code X: 0 S: 0, fringe code X: ' ' S: ' '
observation 3, WETTZELL:MK-VLBA , 3C371 , 07:33:22, quality code X: 0 S: 9, fringe code X: ' ' S: ' '
observation 23, WETTZELL:MK-VLBA , 1806+456, 07:57:39, quality code X: 0 S: 0, fringe code X: ' ' S: ' '
observation 38, WETTZELL:MK-VLBA , 1751+288, 08:16:44, quality code X: 0 S: 0, fringe code X: ' ' S: ' '
Number of observations rejected during analysis: 3
observation 10, WETTZELL:MK-VLBA , 0814+425, 07:40:56, which fits at -385.4 +/- 52.5 ps
observation 15, WETTZELL:MK-VLBA , 1504+377, 07:48:01, which fits at 664.4 +/- 55.0 ps
observation 34, WETTZELL:MK-VLBA , 1504+377, 08:11:41, which fits at 2697.0 +/- 56.0 ps
Other comments: The release is preliminary. The MK-VLBA and WETTZELL log files
were both unavailable at the time of correlation, so the
session will be recorrelated once these log files become
available. The WETTZELL log file was available at the time of
analysis, and it was used during analysis.
Parameterization:
6 parameters:
UT1 offset
atmosphere offset for:
MK-VLBA WETTZELL
clock offset, first order term, and second order term for:
WETTZELL
Clock breaks: None
