This package includes basic data files needed by libswe, the swiss ephemeris. the basic data consists of these files: /usr/share/libswe/ephe/sedeltat.txt.inactive /usr/share/libswe/ephe/sefstars.txt /usr/share/libswe/ephe/seleapsec.txt /usr/share/libswe/ephe/seorbel.txt /usr/share/libswe/ephe/fixstars.cat the swiss ephemeris library can be used without installed data, if the user provides that data in her own private directory and points to it with se_ephe_path.
