Detailed Description

Describes the Region of Ineterest geometry It has basically 9 parameters.

1. zed : central z position of RoI
2. zedMinus : most negative z position of the roi
3. zedPlus : most positive z position of the roi
4. phi : azimuthal angle (radians) of "centre" of RoI at origin in range from [-pi, pi]
5. phiMinus : the most clockwise (negative phi direction) phi value for the RoI
6. phiPlus : the most anti-clockwise (positive phi direction) phi value for the RoI
7. eta : pseudo-rapidity of "centre" of RoI
8. etaMinus : pseudo-rapidity at zedMinus
9. etaPlus : pseudo-rapidity at zedPlus

Parameters

fullscan

if fullscan is true, this RoI will span the entire detector

if full scan, give it full detector limits just in case anyone doesn't bother to check whether the fullscan flag is set Fixme: these fullscan limits probably need to be set from somewhere constistently. static class variables ???

NB: deal with float to double issue This is a hack for the region selector - the RS uses double precision for the phi=pi boundary because the RoiDescriptor only uses a float, so pi is represented as 3.14159274 which is > M_PI so we have to subtract 1e-7 a bit to prevent it failing any phi>M_PI conditions

NB: see comment in double RoiDescriptor::phiPlus()

calculate the gradients - very useful these
