Fix bug in FV z-optimization analysis #145

and tighten z cut based on appearance of leakage gas event

Fixed another bug in the Fitting the bottom corner now yields: Pretty much the same so use 10 GeV which is a bit tighter. |

Fixed another bug right after you approved :(

It's logical 'and' between all 4 lines.
Edit: I think you're right. Max r is missing... also in the last version right?

Based on notebook in https://github.com/XENON1T/SR1Results/pull/21

Hey the fiducial masses for different r bins under current FV version:

Re-optimize z-cut based on bug fixed FV analysis (details below) and tighten z cut to
-8 cmbased on appearance of leakage gas event in SR1 BG data.After review by @lgrandi, I think I may have found a bug where the ER KDE matrix was transposed when it shouldn't be. Now if we look at "er_kde" in the following figure (black line old cut), it seems to make more sense with the population extending across the top instead of down the side (which is not yet the TPC edge) and the bulge transposed now to the bottom-right corresponding to the other corner with large expected materials contribution:

Re-running the notebook and fit results in the following line:
SR0 | SR1
The new cut is significantly shallower and follows the background shape much better.
