I've completed my code that emulated the sector receiver for stand alone testing (i.e. no ORCA needed). It's in this compressed tarball. This code is obsolete. It's only here for historical reasons.

sr.cc is an example front end. It shows how to run the code by filling the tables, reading in some sample data and then using the results.

Here's a file that has about 167 events in it. These events are taken from ORCA and actually can be combined to make tracks. They have different pT, ranging from 1 to 100 GeV/c with a flat distribution.

26 October 2000: New LUTs available! Now we're making progress! These tables work for stations 2-3-4. I have tested them in sector 1 and in sector 2. I have tested all possible wire and strip and pt combinations in front and rear 10 and 20 degree chambers. All agree completely. However, I haven't yet tested station 1. That's next. You will notice that there are two directories now-- sector1/ and sector2/. The LUTs there are different, as different chambers are front or rear. I've tested both and all seem to work.

25 October 2000: Groovy! LUTs that produce identical results for software (i.e. CERN ORCA) and the software simulation of the hardware. The biggest fix? A subsector confusion and correcting distrips for 1/2 strip offsets. Share and enjoy.

24 October 2000: What's new? We now have LUTs for all four stations. Also, these LUTS are identical to those used for the ORCA simulation. This time I've added all the patterns, since some are for high pt and some are for low pt. Before all patterns were present but were interpreted as high pt.

26 September 2000: The new LUTs are available as separate files:

The most recent change is to add in the proper l/r bend lookup bit in the address for local phi.

The old LUTs are available in dated directories.

This file of data is in the "human readable" format. It is also formatted such that for each and every event there are 12 lines. There are three lines for each station, each of which may or may not contain the information to make a correlated LCT. This allows for pileup, as there can be more than one LCT/station/event. However, this is not perfect, as it doesn't yet take into account the fact that the station 1 SR actually has two subsectors. That's another day's work. The format of this file is

event side sector sr mpc strip pattern bend wireGang bx quality chamber

Here's a new file, or rather the old file of data that's been edited by hand to make sure that there are 12 and only 12 lines for each muon. This code is all documented using Doxygen.
