Detailed Description

Title: SpacePointAlg_TimeSort class Author: wketc.nosp@m.hum@.nosp@m.lanl..nosp@m.gov Inputs: std::vector<recob::Hit> (one for each plane) Outputs: std::vector<recob::SpacePoint>

Description: This space point algorithm tries to improve speed by (1) keeping hit collections distinct among planes; (2) sorting hit collections by time; and, (3) having a lookup table for (y,z) coordinate positions. The original use case for this code was with the TTHitFinder, which produces an incredibly large number of hits per plane, making some sorted space point alg more attractive.

This code is totally microboone specific, btw.

Title: TTSpacePointFinder class Author: wketc.nosp@m.hum@.nosp@m.lanl..nosp@m.gov Inputs: recob::Hit Outputs: recob::SpacePoint

Description: This module, TimeTickSpacePointFinder (or TTSpacePointFinder for short) was originally designed to produce a spacepoint object based on hits from TTHitFinder, with the intention to allow for a significant number of ghost spacepoints, where some downstream application would deal with the results.

In reality, it is just a generic SpacePointFinder implementing the SpacePointAlg_TimeSort algorithm.

This code is totally microboone specific, btw.
