IVS Analysis Report for W19142 ($19MAY22XW) This report is the official IVS analysis report that corresponds 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: 54 27 MK-VLBA:WETTZELL and 27 PIETOWN:WETTZELL observations could not be recorded from 07:34 to 08:39 due to a fully recorded module. Number of observations not usable by the software: 2 observation 92, MK-VLBA :WETTZELL, 1651+391, 09:03:29, quality code X-band: 0 S-band: 9 observation 93, PIETOWN :WETTZELL, 1651+391, 09:03:29, quality code X-band: 0 S-band: 9 Number of observations rejected during analysis: 0 Other comments: WETTZ13N was originally scheduled, but WETTZ13N is undergoing maintenance.
