• 77 if 1, output is written to be used with MicrOmegas: running masses for light quarks are written instead of pole masses (necessary for the direct detection calculation) and real rotation matrices for Majorana fermions are used; default is 0
• 86 sets the maximal width which is taken as ’invisible’ in the output for HiggsBoundsand HiggsSignals; default is 0.
• 88 sets a maximal mass of particles which are included in loop calculations; default is 10¹⁶ GeV. Note, this option must be turned in SARAHfirst
