Simulation Settings

Mesut: Ion tail disabled in simulation as it's filtered in FPGA. 

(Defaults in FST are other way around: doIonTailPerPad=1, doSaturationTail=0)

Filter Performance

Tail filter performs poorly, even with very low cutoff (ADC=5).

Likely bug, still tried to better how ADCs are distributed in tail:

How values behave wrt peak distance:

Tail length:

Misc

David discovered bug in noisy pad filter. Fixed in #15278.

Caused by a mismatch in pad indexing between GPU and CPU version.

This was never discovered because GPU and CPU used to have the same bug, but accidentally fixed on GPU in #15001.
