Revisions:
01/28/04 Jason Webb -- Renamed to EEmcSmdGeom, StRoot dependent code moved to a derived class StEEmcSmdGeom. The user interface for StEEmcSmdGeom should remain unchanged. Revision history for StEEmcSmdGeom moved to end of header file.

| const TVector3 & | point, | |||
| Float_t * | dca | |||
| ) | const |
Returns a pointer to the eemc smd strip which is closest to the given point in the specified SMD plane.
- Parameters:
-
iUV 0=smd-u plane, 1=smd-v plane point TVector3 specifying a point on the endcap dca distance of closest approach to the strip priori we do not know if the track is charged or not and how to extrapolate it. must takes care to provide 'point' at the z-location he/she needs the cross point. I realize it is the chicken and egg problem if we want sub-mm accuracy. May be solved by iterations.

| TVector3 EEmcSmdGeom::getIntersection | ( | const StructEEmcStrip * | u, | |

| ) | const |
Return the vector from the specified vertex along the line defined by the intersection of the two planes defined by the two SMD strips. If two strips do not intersect, a warning is issued and -999 returned in the third component.
- Parameters:
-
u a pointer to the structure which defines the smd-u strip v a pointer to the structure which defines the smd-v strip vertex the event vertex

| ) | const |
In a given sector, return the vector from the specified vertex along the line defined by the intersection of the two planes defined by the two SMD strips. If two strips do not intersect, a warning is issued and -999 returned in the third component.
- Parameters:
-
iSec sector number [0,12) iUStrip index of the U strip [0,nstrips) iVStrip index of the V strip [0,nstrips) vertex the event vertex
