Detailed Description

Contains parameters for quality seed confirmation.

Note

Requirements on the number of compatible space-points and impact parameters can be defined for different (r, z) regions of the detector (e.g. forward or central region) by SeedConfirmationRange. Seeds are classified as "high-quality" seeds and normal quality seeds. Normal quality seeds are only selected if no other "high-quality" seed has been found for that inner-middle doublet. For optimization reasons, the algorithm only calls the seed confirmation for a certain inner-middle doublet, in case a configurable minimum number of inner-middle-outer triplets have been found.
