Try fixing dddb tags for ftv4 digi and mdf files
I had noticed a bias in the momentum estimation of long tracks when using these samples.
Thanks to @sesen I was able to fix that bias by switching to a different tag.
Note that while there is no more bias, I don't actually know if these tags are correct, and since they are privately produced it is hard to determine.
I tried GaudiPython and a look at the /Event/MC/Header
shows:
{ applicationName : Gauss
applicationVersion : v51r0
runNumber : 6719250
condDBTags : [(DDDB, dddb-20171010), (SIMCOND, `)]
platformInfo : x86_64-slc6-gcc7-opt:SSE4.1
}{ evtNumber : 68698
evtTime : 0
}
Although as far as I understand these files are FT decoding version 4 which wasn't present in sim-20170301-vc-md100
, therefore I doubt the above info can be trusted.
I'm actually thinking maybe the best would to just remove these files and not use them if we can't be really sure.
fyi: @cattanem since this would most likely also change test output
