From SVT trigger study sample, the average track pair z0 is extracted(fig. (1)) and the new Z template is set to -37.0953 -23.9524 -6.42788 7.03114 24.1606 37.4589
Here's the beam width comparison between previous and new z template.
In the new template, the barrel2 outlier keeps taken out until barrel2 study is done.
(CDF/D0 luminosity vs. HEP set number) shows an interesting pattern as in fig. (4).
I checked individual parameters(fig. (5)-(7) vs. beam duration with store4514(right before 2-week shutdown).
