Class stir::BackProjectorByBinUsingInterpolation: Currently this implementation has problems on certain processors due to floating point rounding errors. Intel *86 and PowerPC give correct results, SunSparc has a problem at tangential_pos_num==0 (also HP stations give problems).
Member stir::EllipsoidalCylinder::EllipsoidalCylinder (const float length_z, const float radius_y, const float radius_x, const float theta_1, const float theta_2, const CartesianCoordinate3D< float > &centre, const Array< 2, float > &direction_vectors=diagonal_matrix(3, 1.F)): angles theta_1 and theta_2 are currently in degrees, while STIR conventions dictate radians.
Member stir::KeyParser::ask_parameters (): breaks with for 'vectorised' keys.
Class stir::NestedIterator< topleveliterT, GetRestRangeFunctionT >: At present, iterator_category typedef is hard-wired to be std::forward_iterator_tag. This would be incorrect if topleveliterT or rest_iter_type is only an input or output iterator.
Member stir::ProjDataInfoCylindrical::sampling_corresponds_to_physical_rings: The value of this variable is currently set by checking if the scanner is a HiDAC scanner. This needs to be changed.
Class stir::ProjMatrixByBinUsingRayTracing: Currently, strange things happen if the z voxel size is not exactly equal to half the ring spacing of the scanner.
