0005 # This cff provides a DTGeometry with the label 'idealForDigi' that is for sure matching
0006 # the ideal one and thus should be used in the digitisers.

0009 # The es_module providing fake (i.e. empty) alignment constants:

0028 ## care: This might lead to a duplication with CSC and tracker equivalents of this file:
0029 #es_source fakeGlobalPositionSource = EmptyESSource {
0030 #    string recordName = "GlobalPositionRcd"

0035 # Comments by GF:
0036 # - In anticipation of the removal of the applyAlignment flag, I'd like to keep it true.
0037 # - Then we would need to get IOVs for the fake alignments,
0038 #   * either using FakeAlignmentSource instead of FakeAlignmentProducer in fakeForIdealAlignmentProducer.cfi
0039 #   * or by using the commented IOV settings above.
0040 # - But this causes problems in co-existence with e.g. GlobalTag: 
0041 #   Both Globaltag as well as FakeAlignmentSource provide IOV - it is not distinguished to provide IOV for 
0042 #   a given label only (e.g. 'fakeForIdeal' compared to '').
0043 # - I'll try to contact framework people for CMSSW_2_2_0 and above.
