| These give the offsets to the first and last active strips in each |
| tower. It has not been assumed that towers are symmetric in X and Y. |
| |
| The units of the transverse dimensions are strip units (228um). |
| |
| Modified 03.08.07 jjr |
| --------------------- |
| Moved TKR_XY_WIDTH_MM to GEO_DB_macros.h, it is really a derived |
| constant defined by the active width of the strips + the 3 interladder|
| gaps. |

| X TILE - Simplification
| -----------------------
| Tile 0 and tile 4 include the 50 mm corner piece. Each X tile overlaps
| its neighbor. We are going to arbitrarily decide that each tile ends/begins
| at the halfway point of the overlap. This assumption leads to not giving
| two chances to particles that pass in the overlap region, but at 99+%
| efficiency, this should be good enough for the filter.
|
| Y TILE - Simplification
| -----------------------
| There is a gap between the Y tiles. We are going to arbitrarily decide
| that each tile ends/begins at the halfway point in the gap. This
| simplification could be a little more dangerous, allowing particles
| that point into the gap to be capriously tested for a tile hit. The
| degree of damage depends on the noise rate. That is, if the tiles are
| quiet, the test will simply fail.

| SIDE ACD TILE GEOMETRY |
| ====================== |
| |
| The following numbers define the limits of Y coordinates for the X+ |
| and X- ACD side tiles. In addition the distance between the nearest |
| tower face to the X+ or X- ACD face is defined. This allows one to |
| extrapolate from the X position in the tower to the ACD face. |
| It is assumed that the tiles are infinitely close, ie the end of one |
| tile is the same as the begining of the next tile. |
| |
| The ACD faces are no longer symmetric. The picture (looking down from |
| the top (i.e. eyesight along the -z axis |

| PROJECTIONS FROM TKR TO SKIRT REGION |
| ==================================== |
| |
| This defines the XY dimensions and Z position of the skirt region. |
| The skirt region is that region between the ACD and CAL which is |
| unprotected by the ACD. Charged tracks can sneak up this area, |
| missing the ACD and thus potentially faking photons in the LAT. The |
| only recourse is to project tracks to this plane and see if they fall |
| into this uprotected region. If so, they are rejected. This causes |
| a loss in efficiency, but there is no other alternative. |
