Typedef Documentation

ACD_M_prj

Typedef for enum _ACD_M_prj.

For a given set of struck ACD tiles, one can construct a mask of which planes should ever be checked. When a track projection is found, the projection type (X or Y) and tower can be used to further limit the scope of the check.

The obvious things appear here, check X-,X+, Y-,Y+ and the TOP planes. There also exists an additional set of masks used to extend the search when the projection is very shallow. In these cases, it is possible that only 2 layers where hit in the tower that is juxtaposition to the struck ACD tiles. It is very possible that the projection was not successfully extrapolated into the that tower and the additional hits where missed. To cover this case, projections with very shallow slopes are allowed to be projected all the way through a tower to an ACD side plane. These are the ACD_M_PRJ_xxS enumerations.

static __inline unsigned int projectXYMtoAcd ( const TFC_prjPrms *  top,
int  zposition,
int  towerEdge,
int  toAcdPlane,
const int *  zSides 
) [static]

Projects an X or Y track projection to the X-/Y- face.

Returns:
The mask of which ACD side tiles could match this projection
Parameters:
top The projection parameters at the top of the projection
zposition Starting z position
towerEdge The left/low edge of the tower in units of strips
toAcdPlane Distance from the strip 0 of the tracker to the ACD plane in units of the strip pitch.
zSides The z positions of the side tiles
There is a parallel routine routine projectXMPtoAcd for projecting off the right/high side of a tower. The calling convention is not the same because the left/lower edge of the tower is, by definition, 0, so the check for leaving a tower on the left/lower side is a simple check against 0. For the right/high side, the check is against the width of the tower (in strips).

The template dispatch mask for this event.
Parameters:
acd_x The bit mask of struck X+/- ACD tiles.
acd_y The bit mask of struck Y+/- ACD tiles.
acd_z The bit mask of struck Z (top) ACD tiles.
The dispatch mask is a bit mask of the possible ACD projections to consider. For example, if no top tiles are struck, there is no reason to even attempt to project the tracks to the top tile face. This calculation is broken out since this is a global property of the event. It is computed once, then used for each tower that has found projections.
