Wrong MC data in file, generated with runMC.C

Wrong pseudorapidity for certain particles which has MC points in TPC.

There are particles with MC points in TPC
and with motherId == -1 (i.e. primary particles)
which have |pseudorapidity| > 3

Pseudorapidity is denoted by eta.
I manually calculated maximum eta for our TPC geometry,
eta = -ln(tan(theta/2))
if max Z = 163.879
and the minimum radius = 40.7
then it turned out that always |eta of primary particle| < 2.1

How to reproduce:

get test.f14.gz file.

It was generated by UrQMD with the following inputfile:

tar 197 79

imp -20.

Then checkout mpdroot version (last for 06 october 2023)

$ git checkout a8816513ca8e3f8715d158e682a5bf3b29c1b4b7

fix Z target to 0:

git diff whole repository

$ git diff

build & install mpdroot

run runMC.C

$ root -q -b 'runMC.C(EGenerators::URQMD,EVMCType::GEANT3,0,"test.f14","evetest.root",0,1000,kFALSE,0)'

it will generate evetest.root

For this evetest.root calculate pseudorapidity with macro printEta.C (attached to the issue)

$ root -q 'printEta.C("evetest.root")'
