### To set a different nominal map, set the following in your .py:

### 3T
#VolumeBasedMagneticFieldESProducer.version = cms.string('grid_160812_3t')
#ParametrizedMagneticFieldProducer.parameters.BValue = cms.string('3_0T')

### 3.5T
#VolumeBasedMagneticFieldESProducer.version = cms.string('grid_160812_3_5t')
#ParametrizedMagneticFieldProducer.parameters.BValue = cms.string('3_5T')


### Run I, 3.8T
#VolumeBasedMagneticFieldESProducer.version = cms.string('grid_160812_3_8t_Run1')
