In a refitting setup, we don't always need all straws available, since given by pattern recognition.
More important is that the material is available.
Not necessary for this, but could be a lot faster, for using a different navigation.
Then we can describe them as boxes in our new geometry.
The endcaps are a smaller problem.
Should be enough to have simple discs.
No need to check for misassignment.
So, pack the endcap straws and pack them into discs.
A: (Xiaocong) Currently problems in the geometry translation.
Make a geo model-plugin, that doesn't use gdml.
There will be a detector description workshop at the end of the month.
Maybe we can learn how to write a translation.
Shouldn't be a problem, because we usually stay below (sharp drop after 45).
Still we maybe need to tune this number.
A: (Andreas) Ganularity is not trivial and they won't line up.
Majority is in the frame structure.
Straws we could maybe even manage in one description.
Let's have this project follow up as a reimplimentation.
Then in a second step (after the QP) have a faster description of the track fitting.
