00005 *** used in VEGAS, the default bin number in original
00006 *** version of VEGAS is 50.
00007 *** a higher bin number might help to derive a more precise
00008 *** grade. subtle point: the value of ncall used in VEGAS
00009 *** should be increased accordingly, otherwise a larger
00010 *** bin number will have no effects or even make the
00011 *** precision lower than before.
