• The noise is now configured as a rate in hits/pixel/s and converted to hits per ROF using the ROF length of each layer. This keeps the noise level independent of the ROF length. The default is 0.2 hits/pixel/s for both TRK and FT3, which corresponds to ~1e-7 hits/pixel/ROF with 18-BC ROFs (default used until now)
• Now it can be passed as configKeyValue as before, but the value to be passed should be 0.2 (or similar values) to simulate a correct amount of noise, instead of the old 1e-7. The definitive noise value is still to be decided, though.
• The ToA of noise digits is now generated uniformly within the ROF instead of being 0 as it was in the first draft
