After having a brief look into creating a measurement with free parameters and an associated volume instead of a surface showed that multiple smaller sub-steps are necessary:
[x] For a measurement in FreeParameters
we will need the possibility to project certain dimensions out from out parameters. Alongside with some other function calls that occur on a ParameterSet
for bound parametrisations make an analogue formalism necessary. This will become the FreeParameterSet
.
[x] Implementing the FreeParameterSet
allows to modify the corresponding parts in the SingleFreeParameters
such that its structure will become similar to the bound parametrisations.
[x] The current measurement only stores surfaces. In order to make the same available for volumes, a different class is required like a FreeMeasurement

Using a TPC/DC for measuring trajectories of charged particles is related to a setup in which the detecting element is located at a different position than the origin of the measurement. Hence the scenario is different to e.g. modules in a tracking detector. A current method for tracking in TPC/DC relies on the construction of surfaces for each measurement at its origin such that the Kalman filter formalism can be applied. However this involves the construction/destruction of many surfaces as well as coordinate transformations of the particle's parametrisation for each surface. In order to avoid this workload, further development is required to allow track reconstruction without surface dependencies for TPCs/DCs. The therefore required steps can be grouped as:
As these modifications strongly interfere with common tracking algorithms, the existing functionality should be preserved and moreover, as the TPC/DC can be considered as special cases, the modifications should be explicitly demanded by the user. The regular applications outside the TPC/DC should be as less affected from the changes as possible.
