Further analysis 91-017A (Lacrosse 2) data

Because the residual for my second point for 91-017A
of last night worried me, I ran SatFit again but this
time also incorporating my data of 17 August. These
are the results:

AZ EL ASP XTRK deltaT Perr
(1) 97.49 47.14 118.26 0.02 0.04 0.030
(2) 102.25 44.06 122.20 0.00 -0.08 0.032
(3) 91.14 49.19 114.34 0.01 0.03 0.016
(4) 96.63 46.27 118.46 0.01 0.18 0.082

Again deltaT of the last point of last night clearly
stands out. However, the results for 17 August do not
indicate this is something recurrent. Hence, it appears
the last point for last night is just anomalous. Such
can happen, it are observational data after all, which
always can have errors introduced by God-Knows-What.
