Configuration Labels

The labels provide an unambiguous ID of specific configuration. The label are defined according to their coverage (using existing letters from software group):

• B = Barrel
• P = forward, Positive endcap
• N = backward, Negative endcap

These are followed by a two-digit version number M.N

• M defines specific subsystem composition. This changes if subsystem is add or removed)
• N labels the geometry (e.g. pixel size, thickness, service material etc). It is changed within a given overall configuration M.

The software group might add a 3rd number (M.N.V) for software version numbers if necessary.

Example: the baseline configuration is: B-0.0, P-0.0, N-0.0.
