Pass0 aligned detector for testing.
TO DO:

  • Some work on module-by-module alignment
  • Improvement for top volume momentum scale and resolution.

However much better Chi2 and track parameters as a whole for studying track reconstruction cuts and algorithms.

Looking forward to testing this. Can you give a presentation at the recon meeting 4/13?

I'll try to!

Do these detector names need to be the same as the name of the det in the directory tree? I think this would just require regenerating this lcdd with the compact from this directory?

They don't need to, but they really should be.

It needs to be the same since once you try to reconstruct any events simulated with this detector, it will look for the detector named in the lcdd file. It will either not be found, or the wrong detector will be picked up. And the reconstruction will most likely crash since the SimTrackerHits won't be inside the Si sensors.

Most of the time we specify the detector anyway right? So it doesn't need to be the same.

Anyway, I think we are all in agreement that it should be changed.

Thank you for spotting this!
Should be fixed.

I don't think we need to leave this here. Just remove it.

Do we need to keep the old survey positions for any reason? Aren't they in an older compact? Maybe it's best to just delete this too.

Hey Omar,
I need the old positions for the back of the detector.

Looks good. Adds new functionality.

Great to see a new detector alignment after the strip mapping bug was fixed!
