            * src/m_surface.cc: Changed rte_pos and rte_los to rtp_pos and
            rtp_los, following renaming of WSVs.

            * src/ppath.cc (plevel_slope_3d): Nadir cases exactly at upper
            longitude end, with 360 deg lon-coverage, failed. Found be
            Richard. This special case now fixed. Fixed also the parallel case
            of nadir measurements exactly at the North pole. (No change should
            be required for lower lon end and South pole.)

            Note that nadir measurements exactly at end points are in gernal
            not allowed. But the two cases above are exceptions.

	* arts-2-1-515

        * src/m_abs.cc (abs_linesReadFromSplitArtscat): Use
	SpeciesTag::Type() to decide on type of species tag.

        * src/absorption.cc (checkIsotopologueRatios): Rewritten. Use
	abs_species only to decide what species to check. For the check
	itself, rely only on the built in species data and the external
	isotopologue ratio data.

        * src/species_data.cc: Corrected outdated H2O comment.

        * src/agendas.cc (abs_xsec_per_species_agenda):
	Added. Name may still change.

        * src/workspace.cc (abs_xsec_per_species_agenda): Added. Name may
	still change.

        * controlfiles/general/agendas.arts: Added defaults for
	abs_xsec_per_species_agenda.
