PTRA: Modify particle names in the MC particle table

The PTRA card assigns an arbitrary particle name to a specific MC integer code. It has to be used, for example, if different MC data sets with contradictory particle tables are read in one job.

The standard procedure to denote the nature of MC generated particles:

• Start with the integer code given for each generated particle.
• Get the corresponding particle name from the MC particle table.
• This name is relevant inside the ALPHA program.

Format

PTRA `part-name antipart-name' iMCcode iMCanticode

Parameters:

'part-name antipart-name'

see 15.4.1. the names for the particle and its antiparticle which have to be used inside the ALPHA program.

iMCcode:

integer particle code used in the MC generator (WITHOUT decimal point and NOT included inside the apostrophes.)

iMCanticode:

integer particle code used by the MC generator for the corresponding antiparticle.

The routine QCPTRA is equivalent to the PTRA card and can be called from QUNEWR whenever a new MC particle table is read in.
