FCC-ALLEGRO, EMBarrel_dz variable used to create fields is defined inside the ECAL compact file

[atolosadelgado]

Hi,

The magnetic field of ALLEGRO is defined in the main compact file as:

    <field name="GlobalSolenoid" type="solenoid"
           inner_field="SolenoidField"
           outer_field="-1.0*tesla"
           zmax="EMBarrel_dz"
           outer_radius="BarCryoECal_rmax-CryoBarrelBackWarm-CryoBarrelBackCold">
    </field>

however, the variables EMBarrel_dz, BarCryoECal_rmax and CryoBarrelBackCold, used to calculate its zmax and outer radius are defined in the compact file of ALLEGRO ECAL.

Shall we refactor this, moving these global variables that define the outer radius and zmax of the ECAL and magnetic field to Detector Dimensions compact file?
