This refers to updating geometry for the following detectors:
See this page for general information.
The geometry is built in the detector converter as specified by input from the compact.xml file. Depending on the detector there is more of less information in the compact.xml. If you want to change some aspects of the geometry that is not available in the compact description please contact the experts.
The compact contains a set of <millepede_constant name=XXXXX value=Y> which is read in and applied to the nominal setting of the geometry. These constants can be updated by hand or created from a Millepede output file.
The name of an alignment constant "ABCDE" is described below for the Test Run geometry
Letter | Allowed values | Meaning |
---|---|---|
A | 1-2 | 0: TOP, 1:BOTTOM |
B | 1-3 | 0: sensor translation, 1: sensor rotation, 2: support plate rotation |
C | 1-3 | if B=0 or 1 => 1: sensor measurement ("u") direction, 2: sensor unmeasurement ("v") direction, 3: normal to sensor plane direction ("w") if B==2 only 1 is allowed => 1: |
DE | 01-10 | Sensor id. |
