MadWeight: VEGAS question. What is 'wgt'?

Asked by Max Christian

Hi, I've been looking into the MadWeight implementation recently.

In vegas.f, at the function call: f=f*fxn(x,wgt)
What exactly is 'wgt'?
Any explanation would be greatly appreciated :)

Thanks!

Max

That’s the jacobian associated to the VEGAS grid.

Cheers,
