SoLID CLEO (based on CLEOv8 field map)

CLEOv8 field map is based on more realistic design with CLEO-II.

The magnet and yoke will fit both PVDIS and SIDIS/JPsi configuration.

The detector has various small change to fit into new design, please refer to the change at slide 7 and 8 of CLEOv8 update pptx pdf
