StFtpcDriftMapMaker replaces St_fmg_Maker. It is a standalone program.
The heart of the code are the algorithms of both magboltz1 and 2. In the standard version, magboltz 1 is used because of the much shorter calculation time.
The baseTemperature, basePressure and pressureOffset parameters come from the Calibrations_ftpc/ftpcGas table in the STAR MySQL offline database.
StFtpcDriftMapMaker is written in C++ by Holm Hümmler and is maintained by Janet Seyboth. To do the gas calculations (actually the bulk of the work), it uses the C++ Magboltz program package, which calculates the drift properties at different points in the FTPC volume.

To run StFtpcDriftMapMaker:
mkdir Work cd Work ln -s StRoot/StFtpcDriftMapMaker/macros/FtpcDriftMapMaker.C FtpcDriftMapMaker.C root4star -b -q FtpcDriftMapMaker.C(map,factor,deltaAr)
|map||select magnetic field values||Default: = 2|
|= 1||use constant field values|
|= 2||use mapped field values|
|factor||field scaling factor||Default: = 1.0 (full field positive)|
|> 0.8||full field positive|
|< 0.8 && > 0.2||half field positive|
|< 0.2 && > -0.2||zero field|
|> -0.8||half field negative|
|< -0.8||full field negative|
|deltaAr||the change (+/-) in the percentage of Ar from 50%||Default: = 0.0|
