In particular, many InChIs are known wrong, and we have skipped several hundred lines because we did have no InChIs for their species at all. .. _CASA Offline Splatalogue: https://safe.nrao.edu/wiki/bin/view/ALMA/CASA_Offline_Splat_listcasa_lines.data This is a rendering of the `CASA Offline Splatalogue`_ in a draft SLAP2 service, mainly intended to enable verification of the standard.
