Post-production Muon Reconstruction
Yes, muon reconstruction can be re-done using the pad banks. Muon raw data banks are kept on the pads as well as the compressed calorimeter (QTOW) and track (QTRK) banks. The muon-to-track and muon-to-calorimeter linker expects TOWE and TRKS you need to include the calorimeter and track decompression modules before the muon reconstruction module. You will need to include all the relevant modules in your Build_Job .UIC file and run them in the correct order in your Analysis_Control path.
Use of CMUSWM
Due to an obscure and hard-to-disentangle interdependance of one piece of code on another, post-7.10 versions of CMUSWM require the user to set up the QFL random number stream.
Make sure sure the offline utility setup is done by Analysis_Control in your .EXE. (I think this is done by default, but to make sure, you might want to add the following line -- set util/offline=on -- to your Build_Job .UIC file.)
Then somewhere in your code before you call CMUSWM (grand init is the right place), include the following lines of code.
CMUSWM also uses the EXPTYP variable in JOBSTA.INC to determine which version of the detectors to simulate. If you're using real data, this is set up for you by Analysis_Control. For Monte Carlo data, I think A_C also sets it up for you, but it might not be what you want. If you're using CMUSWM stand-alone, you should modify it yourself to define the right detector. (See A_C$LIBRARY:ANCOMP_EXP_ID.INC.)
center>Trigger Separation in Offline Muons
The separation is quite good. The following plot shows the fidicual separation of CMUP and CMNP triggers using offline information. The CMU trigger tower is decoded from the bank and plotted separately for CMNP and CMUP triggers. The trigger towers belonging to the CMNP triggers are boxed in the plots.
This data comes from the IA W sample. No other cuts have been made.
