IVS Analysis Report for Q18232 ($18AUG20XK) 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: The correlator could not find any fringes for NYALES20. They have contacted NYALES20 to investigate the cause. Number of observations rejected during correlation: 0 Number of observations not usable by the software: 0 Number of observations rejected during analysis: 20 The WETTZ13N:WETTZELL baseline was deselected to comply with current procedures at the GSFC VLBI Analysis Center. Other comments: The correlator noted that SESHAN25 had RFI in S-band channel SR5U. Parameterization: 10 parameters: UT1 offset atmosphere offset for: SESHAN25 WETTZ13N WETTZELL clock offset, first order term, and second order term for: WETTZ13N WETTZELL Clock breaks: None Session Statistics Observations: 120 scheduled (from all stations---includes NYALES20) 60 scheduled (from available stations---does not include NYALES20) 60 correlated (included in the database) 60 recoverable (usable in Solve/nuSolve) 40 used Session fit: 63.384 ps UT1 formal error: 17.38 microsec Source Performance Number of Observations Scheduled Correlated* Used 0602+673 6 3 2 OJ287 6 3 2 0955+476 6 3 2 1053+815 6 3 2 1156+295 6 3 2 3C274 6 3 2 1300+580 6 3 2 1418+546 6 3 2 1726+455 6 3 2 0800+618 6 3 2 0529+483 6 3 2 0729+259 6 3 2 1040+244 6 3 2 1053+704 6 3 2 0016+731 6 3 2 0736+017 6 3 2 0821+394 6 3 2 1030+415 6 3 2 1504+377 6 3 2 1849+670 6 3 2 ------------ --------- ---------- ------ Source Total 120 60 40 * Correlated means included in the database.
