Biasing

Q:

I am doing some biasing using the weight window (with command WW-FACTOr). But I have done a test without biasing and I get the same result! Why?

A:

Check that you have in input a WW-THRESh card. It is compulsory when using WW-FACTOr, otherwise the two energy thresholds are set equal to zero, and it is as if the weight window was not there.

Q:

When simulating electromagnetic showers of high energy, it takes very long time. Which biasing should I use to increase performance?

A:

If you are not interested in fluctuations or correlations, use Leading Particle Biasing (see EMF-BIAS on the Manual). For shielding calculations of high energy accelerators, the use of this biasing feature is very effective.

Q:

I am interested in a correlated analysis on a event by event basis. Is there anything which I must define in the input for that purpose?

A:

You must define a "fully analogue" simulation with WHAT(2)<0.0 in the GLOBAL card.
