UnexpectedMagneticField message in Pixel2D template (Run3 data at 0T)

[boudoul]

Hello
I noticed when reconstructing a run from MWGR this message :

%MSG-w UnexpectedMagneticFieldUsingNonIdealPixel2DTemplate: PostModuleEvent 27-Oct-2020 15:14:15 CET Run: 334393 Event: 9562884
Magnetic field is 0 Template Magnetic field is 3.8

I'm just reporting here in case this is the sign that something needs to be fixed in order to have the right config when taking data at 0T (= the current case at P5 and will be important when commisioning the full detector during CRUZET later in 2021). Is this a known problem ?

How to reproduce ? Easy : running on 1 event of the workflow 138.1 (with a valid certificate to access data)
runTheMatrix.py -l 138.1 --command "-n 1"

Thanks.

For now this is WONTFIX:

1. Pixel Tracker is not part of MWGR
2. 2D template reco is irrelevant for cosmics anyway

For more discussion:

#26940

Will eventually be fixed before start of data-taking for collisions.

• This has been fixed in Remove 2D pixel template B field warning for 0T #34390 so the issue can be closed!
