This file is somewhat of a kludge. The offline needed access to some of the values in here that were not included in the CDM. (Well they were, but it was the integer version of them, which lost some accuracy when converted back to the floating point versions. The correct thing to do would have been to expand the information in the CDM to include the necessary data. However, this was a lot more work and not backwardly compatiable. Given the lateness in the game and the fact that this constants are not likely to change, this was deemed to be an unfortunate, but semi-reasonable compromise. HOWEVER, it is still a compromise. CDMs are meant to contain data that is either

• Time dependent
• Configuration dependent (For example, before the LAT was built, the constants in here where, by definition, unknown. However, there was Monte Carlo data which had some definition of the detector geometry. In that case, a different CDM was read into the FSW code. Statically compiling code with this file defeats this scheme.)
