Empty Hexagons

The ABS Hexagons consists of arrays of regions:-

• Region IDRG_HEX_EMPTY, a hexagon prism, representing a missing PMT. The serial number is the PMT serial number (PMT numbers actually number panel positions so even missing PMTs are numbered).

A empty hexagon is an hexagonal prism filled with the same media in which the panels are immersed. A belly plate rope may be embedded.

User Control

None. Currently it is not possible to pick points randomly in an Empty Hexagon; all hexagons have PMTs. The volume associated with this region is set assuming that 66 PMTs are missing. This ensures correct weighting if picking points in IDRG_EMPTY_HEX and other water-filled reqions, e.g. IDRG_PAN_ZONE, simultaneously.
