Counting Room

The counting room consists of one region:-

• Region IDRG_COUNTING_ROOM, representing the low density area above the inner darkness.

For SNO the shape is a barrel, there is no counting room for Mini-SNO. For the accuracy of this shape see the inner darkness section.

User Control

The user can disable this region so long as the urylon, shotcrete, and rock regions are also disabled. In this case the inner darkness terminates in the outer darkness.
