Added ResourceType and NamingAuthority. Changed http to https in top-level schemaLocation attribute. Fixed version number separator in top-level schemaLocation attribute. Matched version number in schemaLocation attribute to updated value in Version tag. ZCB 2025-12-04T13:29:29Z Added MetadataRightsList and RightsList(s). Updated to 2.7.1. ZCB Each table (CSV file) captures the numbers of counts of arriving energetic neutral atoms, as integrated over a full 8-day orbit, for a single IBEX-Lo energy step, for one of two categories of species (hydrogen, oxygen plus carbon, the latter being labelled "Oxygen" in file names). Numbers of counts are given in 360 1-degree bands in spacecraft spin phase. Each table is CSV-formatted Excel. Each subdirectory is for a given energy band and has the tables (files) for each of several orbits for each of the two species categories.
