Hall D Geometry Data Base: Focusing DIRC detector
***********************************************
version 1: Initial version -rtj
version 2: Updated version, refined geometry of the optical box
added pixels
added volume ids to use for the reconstruction
version 3: added as-built aluminum supports;
implemented dimensions of each individual short bars;
each bar box and each optical box is now unique (not copied from prototypes)

DIRC Bar Configuration (DCBR)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
DCBR##: configuration for DIRC bar number ##
- each long-bar consists of 4 short-bars, each ~1.225m, labeled as A,B,C,D
- labeling convention adopted from SLAC: wedge, A, B, C, D, far-end mirror
- dimensions of each short bar are taken from spreadsheets from SLAC and implemented
The convention adopted for component alignment is as follows (in GlueX coordinate system):
- x-direction: the bar-side of the wedge is at 490.015,
and all other components are put sequentially starting from there
- y-direction: aligned against the lower edge. The center of each bar
goes from -19.3325 to 19.3325 with 3.515 increment
(nominal bar width 3.5cm + 150um bar-to-bar spacing).
each component is then aligned such that the lower edge is at
-1.75 w.r.t. center.
- z-direction: aligned against downstream side, such that the downstream face of
the bars and wedges are at z=1.7 w.r.t. DCBR## z position. This is
supposed to be how those bars were assembled at SLAC
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
