BEGINRELEASENOTES

• Adding a CartesianGridUV segmentation class, providing for a stereo readout, i.e. a readout at an angle w.r.t. the axes of the sensitive volume.
• The class is a straightforward derivation of CartesianGridXY, with only few extras needed to register the angle parameter and execute the rotation.

I can add that most of the modifications from CartesianGridXY to CartesianGridUV are obtained with the following sed patch:

sed -e "s/\([^\.]\)X/\1U/g" -e "s/\([^\.]\)Y/\1V/g" -e "s/_x/_u/g" -e "s/_y/_v/g" -e 's/"x"/"u"/g' -e 's/"y"/"v"/g' $file

where $file runs through:

DDCore/include/DD4hep/CartesianGridXY.h DDCore/include/DDSegmentation/CartesianGridXY.h DDCore/src/CartesianGridXY.cpp DDCore/src/segmentations/CartesianGridXY.cpp

I don't think we should call this cartesianUV, because this is not a carthesian, Orthogonal Coordinate system, any more. Rather SkewUV?

I see this really is just a rotation around Z, and the U V and Z axis are still all orthogonal.

Thanks!
