Recently it was discovered that an update is needed in the numbering of the Rich1 Mapmt modules. This update is implemented here. The related details from hardware are available in a recently created EDMS document https://edms.cern.ch/document/2741320 . The effect of this update is a rotation of each column of modules by 180 degrees. In addition the modules at the corners which are farthest away from the beamline, have no ECR.
Requires LHCb!3598 (merged) Rec!2925 (merged)
