USNO Analysis Report for Q18323 ($18NOV19XK) 
       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:
    NYALES20 - Did not participate.
    WETTZELL - Started late, missing the first 7 scans. First scan observed had
               0-codes.

Number of observations rejected during correlation:   19

    The first 7 scans of ISHIOKA :WETTZELL were missed.
    The first 7 scans of WETTZ13N:WETTZELL were missed.
    observation  5, ISHIOKA :WETTZ13N, 0059+581, 07:10:30, no S-band in database
    observation 13, WETTZ13N:WETTZELL, 2000+472, 07:18:04, no S-band in database
    observation 19, WETTZ13N:WETTZELL, 0016+731, 07:21:18, no S-band in database
    observation 61, WETTZ13N:WETTZELL, 2000+472, 07:45:27, no S-band in database
    observation 82, WETTZ13N:WETTZELL, 1300+580, 07:58:58, no S-band in database

Number of observations not usable by the software:     2 

    observation  9, ISHIOKA :WETTZELL, 1418+546, 07:16:03, quality codes - S:0, X:0
    observation 10, WETTZ13N:WETTZELL, 1418+546, 07:16:03, quality codes - S:0, X:0

Number of observations rejected during analysis:       0 

Other comments: ISHIOKA was used as the clock reference and a baseline clock offset
was added to the WETTZ13N:WETTZELL baseline.

Parameterization: 
   8 parameters: 
     UT1 offset 
     atmosphere offset for:
         ISHIOKA WETTZ13N WETTZELL
     clock offset (0), first order term (1), and/or second order term (2) for:
         WETTZ13N (0,1) WETTZELL (0,1)

Clock breaks: None
