[neutron-mc] How to set parameters "dist" and "xw/yh"?

[wokaoyan1981]

Dear colleagues,

Why is it necessary to set parameters "dist"  ,"xw" and "yh" of the component Source_Maxwell_3?

How to set them with regard to a source followed by a straight neutron guide?

Please shed light on them thoroughly.Thank you!
