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 2025-12-04T13:29:22Z Added MetadataRightsList and RightsList(s). Updated to 2.7.1. ZCB Each record captures the number of arriving ENA's of a specific energy band, coincidence type, and spin phase. Data for each full ~15s spacecraft spin are given at each of 60 spin phases in sequential records, with the J2000 right ascension and declination for look directions corresponding to each spin phase being given in the corresponding record. Also included in each record are a time tag (seconds since 00:00 UT of January 6, 1980), the IBEX location, ENA energy band and coincidence type. Positive species identifications are not made, but most arriving ENA's are hydrogen atoms. Data files are given for each 8-day orbit and for each of the 6 IBEX-Hi energy bands. The data files are in ASCII.
