Some progress has been made to implement further patrs of the PXL detector and its support in my 'stand-alone' TGeo implementation.
The slides attached has some old material but also newly added improved descriptions. As mentioned on on of the last slides thare is work to do to implement thi in agml.
The C++ code used to generate and run this can be found in
/brahms/u/star/hftgeom/
It runs under root v5.32 I have not checked how it works with the default STAR version (i.e. reason for using my other accounts where I
have complete control over the enviironment and root)

Dec 30,2012 An offset error has been fixed. It is now pretty close to the SW model.
