std::vector<Acts::GeometryIdentifier> ActsExamples::HoughTransformSeeder::Config::geometrySelection

For which part of the detector geometry should space points be created.

Only volumes and layers can be set. Zero values can be used as wildcards to select larger parts of the hierarchy, i.e. setting only the volume selects all measurements within that volume. Adding a single identifier with all components set to zero selects all available measurements. The selection must not have duplicates.

std::vector<unsigned> ActsExamples::HoughTransformSeeder::Config::hitExtend_x

Initial value:

= {
        1, 1, 0, 0, 0, 0,
        0, 0, 0, 0}

For each assumed q/pT (y) we find the appropriate phi (x) bin for a hit. But if extend = 2 (for example) We then fill in addition 2 bins to the right, and 2 bins to the left, so 5 bins and not just 1

unsigned ActsExamples::HoughTransformSeeder::Config::houghHistSize_x = 7000

Size of the houghHists. One obvious concern with this being too big is that it will take up more memory But the bins of the houghHist are looped over in two places as well, so there are CPU performance issues, too The first is just when finding the bins and hits that provide candidates, so the loop is over x*y bins. The other is when filling the bins. The loop is over y bins, and for each y bin we find the min and max x for each hit

std::vector<std::string> ActsExamples::HoughTransformSeeder::Config::inputSpacePoints

Input space point collections.

We allow multiple space point collections to allow different parts of the detector to use different algorithms for space point construction, e.g. single-hit space points for pixel-like detectors or double-hit space points for strip-like detectors. Note that we don't need spacepoints (measurements can be used instead)
