Detailed Description

: The muon space point bucket represents a collection of points that will bre processed together in the pattern seeding.

Buckets represent a a collection of hits that are close in a layer & sector of the muon spectrometer The area covered may varied across the different regions of the spectrometers & may also partially overlap with other buckets close-by.
