The current S1 patterns map was interpolated and extrapolated from only 10 bins in z. The new map now has 60 bins before interpolation and thus have a sharper LCE distribution through the PMTs at the LXe/GXe transition zone where the issue was most visible.

The map is still created with MC v0.2.1/v0.3.0 (nearly equal to v1.0.0) from 1e9 events.
The map is tested in MC production with 5e6 events without FAX related errors. The result looks good. Something more to do?
