Detailed Description

The payload containing the momentum threshold to disable the particle hypothesis in the track fit.

If the track momentum (from the seed) is greater than the hypothesis threshold, the particle hypothesis is disabled; if the momentum is lower, the particle hypothesis is used. Pion (default hypothesis) threshold has to be always infinite (large, always enabled). The values are expressed in GeV/c.
