Determine whether the layer is X(1) / U(2) or V(3)

Order the strips such that the first and second pair consist each of crossing strips

The second pair is parallel

Assign the first measurement of each layer to calculate the linear transformation

Habemus valid strip quartett

Function to calculate the muon crossing

Reserve space for 200 seeds

The two channels are too narrow. Same conclusion holds for all previous hits from this layer combined with the next ones of layer 1

The opening angle of these two channels is just too wide

The first or the second one can cross with the third one

Reject combinations that consist only of 1 strip clusters

We will revise this requirement in the near future. Keep the block for the moment

Removes clusters from high activity areas in the detector.

The micromegas are slobbering quite a lot in the 2023 data taking leading to uncopable comptuing times. The burst vetoing aims to mitigate this situation. A histogram with a bin width of m_ocupMmBinWidth is defined Hits are filled into the accoring bin using their channel number Bins with large activity are then cleared. In the second step, pairs of bins where their sum is too exhaustive are removed.

Define the number of bins

Fill the measurements into the histograms

Apply the single bin cleaning

Apply the pair wise bin cleaning

Copy the rest over
