L1DctSim, L1DctData, L1DctDataP (February, 1998)

L1DctSim contains Digi-making code for the drift-chamber trigger simulation. This code reads from common blocks in trgDC and creates three types of Digis, corresponding to the types of DCT data. L1DctData contains the Digi classes. The status of each Digi is:

• L1DTsfDigi: This Digi contains as its data members the superlayer, pivot-cell index, time, and 16-bit segment "address" for each segment found in the trigger. It also provides accessors to look up information about each segment such as phi position, latency, and a list of which DCH cells in the segment had hits. This Digi is completely implemented, and persistence is scheduled to be implemented in release 6.1.0.
• L1DBltDigi: This Digi contains a time history of phi maps for A tracks and B tracks. A first (transient) version is scheduled for Spring 1998, and persistence will be implemented shortly thereafter. Nobody has use for this Digi, to date.
• L1DPtdDigi: This Digi contains information about A' tracks. A first (transient) version is scheduled for Spring 1998, and persistence will be implemented shortly thereafter. Nobody has use for this Digi, to date.

Needed from others:

• Nothing.

Work to be done:

• Implement transient BLT and PTD Digis
• Implement persistence for BLT and PTD Digis
• Modify TSF Digi (or trgDC) to provide needed lookup tables in the absence of L1 simulation
