The vector hit data results from the coordinate transformation process and is contained in a cell structure. This cell structure is passed on to a fan-out process ( buf.fan) which appends two crates worth of vector hit data together and strips off the cell headers. The vector hit data in its cell structure may also be packed into a crate structure for readout and online monitoring. The vector hit data contains the following information for each vector hit.
Words 7-14 will be filled only if one or more hits are matched. Words 7-11 will only have meaning if two or more hits are matched. See Reference 6 for a full definition of the SLT parameters and angles.
