See question 268443.

Here are the basic instructions.
Main point -- You can scan over a parameter that is not a model parameter!

 So, for example, you could add the lines:

Run parameter: rtS
Run begin: 7
Run step size: 1
Run n steps: 2

to your batch file even though rtS is not a parameter of the model. (You could name it something different if you like.) Then, the momenta can be made functions of the scan parameters. For example,

p1: 1000*rtS/2
p2: 1000*rtS/2

This will plug the scan value of rtS in and then calculate the value before running CalcHEP.
