Missing energy, mass, momentum

Input arguments:

ICLASS

described in 10.3.

ITOTAL

= 0: Missing energy, etc. is calculated with respect to the total energy vector (0.,0.,0.,QELEP). > 0: Calculation is done with respect to vector ITOTAL.

Results:

PMISS

Missing momentum.

'miss-vector

vector containing missing momentum, mass, and energy.

Error conditions:

• Total energy > LEP energy QELEP.
• Missing momentum > missing energy.
• In both cases, the output vector contains energy = PMISS and mass = 0.
