filterFlaga flag containing the following information: the 1st digit is a flag of filter used to preselect the kink candidate (from 1 to 5); the 2nd and 3rd digits form a flag of the two tracks combined fit result (from 0 to 15, 18, and 19) if the first digit is 1 or 2; if the first digit is 3 to 5, then the second digit is equal to 1 when the distance between daughter and mother track at vertex bigger than the cut in KinkFitter; the 4th and 5th digits together show the number of reassigned hits between tracks (from 0 to 32); the sign shows from which track the hits were taken (- from daughter, + from mother).

◆ m_filterFlag

short m_filterFlag = 0
private

The filter flag of the kink.

1st digit represents the filter in KinkFinderModule used to preselect the kink candidate (from 1 to 5): Filter 1, 2, 4, and 5 of KinkFinderModule are saved as 1 (track pair that has close endpoints); Filter 3 and 6 of KinkFinderModule are saved as 2 (track pair selected with daughter Helix extrapolation); Filter 7, 8, and 9 of KinkFinderModule are saved as 3, 4, and 5, respectively (split tracks). Split-track kinks (3-5) have worse resolutions compared to track-pair kinks (1-2). The filter number (3-5) for split-track kinks might be helpful to supress false track splitting with ML. The kinks created from track pair that has close endpoints (1) might have better resolutions than ones selected with daughter Helix extrapolation (2).

2nd and 3rd digits for filter 1-6 of KinkFinderModule represent the result of combined fit (from 0 to 15, 18 and 19); 19 means fit of combined track is failed; 18 means combined track has less n.d.f. than mother track; if <16, it should be understood in bit form, where the results of following comparisons are 1 or 0: 1st bit: p-value of combined fit > p-value of mother fit; 2nd bit: p-value of combined fit > p-value of daughter fit; 3rd bit: n.d.f. of combined track > n.d.f. daughter track; 4th bit: p-value of combined fit > 10^{−7}.

2nd digit for filter 7-9 of KinkFinderModule shows 1 (0) if the distance at the fitted vertex is bigger (smaller) than required cut in KinkFitter.

4th and 5th digits together form a number of reassigned hits (from 0 to 32); If more than 32 hits are reassigned, set 32.

The sign shows from which track the hits were taken (- from daughter, + from mother).

The content of the m_filterFlag may change, please, refer for the details to KinkFitter.cc.

Example 1: -23181: -2318"1" track pair was preselected with filter 1, 2, 4, or 5 (mother track and daughter track end points are close); -23"18"1 the exit code of combined fit is 18, so the combined track has less n.d.f. than mother track; "-23"181 – 23 hits were reassigned from daughter track to mother track Example 2: 2015: 201"5" kink was created from split track selected with filter 9 (track did not pass neither mother nor daughter preselection criteria); 2"01"5 the code 1 means that the distance at the fitted kink vertex is larger than the set cut; "2"015 – 2 hits were reassigned from mother track to daughter track
