Hi,

I have a version separated but I have not put into my shared "FWD" library yet. I'll check that everything is working and do it shortly.

Best,

Daniel

Thanks for the clarification, Daniel, Te-Chuan.

What is the status of the Fast Simulators? Have the FST and sTGC codes been separated?

I think it is better to keep them separated, same for the simulators, so that one can update the FST or sTGC software without worrying about affecting the other one, or how to keep the code synchronized. This is what we did for HFT, with PXL/IST/SSD separated. I brought this idea up of separating FST and sTGC in the simulation software at a forward upgrade meeting about half a year (?) ago, and Daniel Brandenburg (cc’ed) certainly supported it and agreed to do the splitting for the simulators
