[Comphep-common] transverse mass

[Shao-Feng Ge]

Hi everyone;

I'm trying to add cuts on transverse mass and also plot it's distribution.
But I found that this kinematic function is not incorporated in CompHEP.
I'm wondering if any one of you has tried this before. I tried to add this
function. But it seems the manual is too old. I followed the corresponding 
instruction but it doesn't work. 

I want to know which source file I should modify. There are two usrFun.c files.
One in the working directory and the other in the installation directory. 
That would be great if anyone of you can provide me an example or useful 
manual. The version I'm using is 4.4p3-gcc411. 

Thanks!
