IDs for LHAPDF PDF sets (https://lhapdf.hepforge.org/pdfsets).
For 2016/17/18 UL, PDF set with ID 325300 is recommended (https://monte-carlo-production-tools.gitbook.io/project/mccontact/info-for-mc-production-for-ultra-legacy-campaigns-2016-2017-2018).
In this case, MadGraph5 v2.6.1 is recommended (version specified in external/genproductions/bin/MadGraph5_aMCatNLO/gridpack_generation.sh).
For "normal" 2016 (2017/18), PDF set with ID 292000 (320900) should be used. Though, there are reports that 320900 can generate large negative weights and this needs to be investigated further for this model.
