deltaR double-counts combinations when given multiparticle labels as arguments

[Rakhi Mahbubani]

Dear MA5 team,

Please could you fix the definition of deltaR so it automatically excludes double-counting for multiparticle label arguments?

thanks,

Rakhi

This won't be fixed as this goes against the way multiparticle works in the normal mode of running (and would require too heavy changes). The best way out is to use the expert mode.
