USNO Analysis Report for I18023 ($18JAN23XU) 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: None. Number of observations rejected during correlation: 3 KOKEE did not observe the last three scans due to issues with its az motor controller. Number of observations not usable by the software: 2 Scan 023-1840: FQ = 0 on S and X -Band due to low SNR, source 1144+402. Scan 023-1909: FQ = 0 on X-Band due to low SNR, source 2209+236. Number of observations rejected during analysis: 0 Other comments: The error bars were similar sizes, suggesting that a few bad points had snuck in the solution. However, no machinations could satisfactorily adjust the solution, and no modifaction was made. Parameterization: 5 parameters: UT1 offset atmosphere offset for: KOKEE WETTZELL clock offset (0), first order term (1), and/or second order term (2) for: WETTZELL (0,1) Clock breaks: None Session Statistics Observations: 20 scheduled 17 correlated (included in the database) 15 recoverable (usable in Solve/nuSolve) 15 used Session fit: 69.430 ps UT1 formal error: 15.46 microsec Source Performance Number of Observations Scheduled Correlated* Used 0016+731 1 1 1 0716+714 1 1 1 0955+476 1 1 1 1015+359 1 1 1 1040+244 1 1 1 1101+384 1 1 1 1144+402 1 1 0 1300+580 2 1 1 1418+546 1 1 1 1803+784 1 1 1 1800+440 1 1 1 3C371 1 1 1 2113+293 2 1 1 2144+092 1 1 1 2209+236 1 1 0 2214+350 1 1 1 2229+695 2 1 1 ------------ --------- ---------- ------ Source Total 20 17 15 * Correlated means included in the database.
