Planarity of the membrane (cont.)
Hejdar did the calculation for accounting delays on membrane of light from defusers.
See
https://drupal.star.bnl.gov/STAR/system/files/membrane.pdf
I just add more accurate accounting shadow due to Inner Field Cage.
Taking into account light delays for diferent rafts and defusers from

Delays for laser rafts.
T-zero is a moment, when a laser arrived to TPC wheel surface.
All other numbers corresponded to time for laser light to propagate to particular raft (TPC sector).
Estimated error in table 0.1ns
West: sector 2 4 6 8 12
Time(ns) 10.33 3.34 6.14 13.11 17.31
East: sector 14 16 18 20 22 24
Time(ns) 19.88 12.95 5.97 3.18 10.17 17.14
