There was a suggestion by Rongrong to remove superseded datasets that we do not use anymore.
This might have already been done, but here is the list:

production_pp200long2_2015::P16id::SL17i (st_mtd, superseded by SL19c)
production_pp200trans_2015::P16id::SL17i (st_mtd, superseded by SL19c)
production_pp200long_2015::P16id::SL17i (st_mtd, superseded by SL19c)
production_pp200long3_2015::P16id::SL17i (st_mtd, superseded by SL19c)
AuAu_200_production_2016::P16ij::SL16j (st_physics, superseded by SL18f)
