63 | * This is just an example of a possible user written source routine. * | |
64 | * note that the beam card still has some meaning - in the scoring the * | |
65 | * maximum momentum used in deciding the binning is taken from the * | |
66 | * beam momentum. Other beam card parameters are obsolete. * | |
