YBOS bank name, number - (CMUS,n_s)

Central Muon Detector Segment Attributes

This bank contains the reconstructed line segments for the central muon chambers. The parameters values are in C$INC:CMUS92.INC . An example of a routine that unpacks this bank is C$MUO:CMUSPT.CDF .

Notes:

     1.  Central muon segments are straight lines.  For a set of  hits
         in a wedge, two lines are fit:  one in the zy plane (slpz*z +
         intz) and one in the xy plane (slpx*x +  intx).   Coordinates
         are  in  'local  wedge  coordinates',  where  the xz-plane is
         parallel to the chamber planes, x=0 is in the middle  of  the
         chamber  (in phi), y=0 is at the bottom plane of the chambers
         (sense wires at the smallest radius from beamline), and z  is
         the same as for CDF standard coordinates.

     2.  Segments may  be  made  from  2,  3,  or  4  hits  in  either
         direction.   A  segment  can  have  less  than  4 hits due to
         geometry, ADC overflows, inefficiency, etc.   The  simulation
         particle id is non-zero only for Monte Carlo data.

     3.  For every CMUS bank there is a CMUL bank with the  same  bank
         number.  The CMUL bank lists the CMUE element numbers used to
         form the segment.  The banks are written  by  the  subroutine

which  is  called  by the Analysis Control module defined by
