Hi Hugo,

 

Thanks for the set of slides – here are some of my initial thoughts. BTW I am happy to help with this also, if it would be useful to divide it up. Just let me know if I can help.

 

1. I guess this would only account for static and average distortions if they are loaded at InitRun. Is my understanding correct? How would we handle the event-by-event fluctuations, would this be a histogram (or whatever structure) that gets updated in another module and could be stored as a part of these objects?
2. For TpcDistortionCorrection, we discussed yesterday/today that in order to apply a correction to a cluster we will already need to know what track it is on and have the track projection from the silicon+TPOT. Maybe I am misunderstanding, but how would this interface with PHCASeeder? I would think we would need to also implement the machinery from the ClusterMover into this (which is maybe what you were intending).

 

Joe

Hi Ross, Tony others

Unfortunately I have to leave early at today's TPC calibration meeting. I had a few slides to discuss what I would like to implement for "on demand" distortion correction, that can be used wherever necessary (e.g. CA seeding, cluster mover). Maybe we can discuss that offline instead ? The idea is to use similar code as is done with the ACTS surface map, and the local-to-global transformations.

Comments welcome

I’m triple booked at 11, so if the tracking discussion can wait until 11:10 I would appreciate it – otherwise go ahead and I’ll join when I can.

Hello Ross,

 

We discussed tracking workflow with distortions yesterday in the tracking meeting.

 

I posted a couple of slides on that discussion.

 

Cheers

Tony

Dear Distortions Folks,

This is a reminder that the distortion meeting will take place tomorrow at the usual coordinates and time, 11AM EST.  I believe there are updates to discuss on both the tracking integration and readout simulation fronts, and other updates are encouraged, as always.
