These directories contain data from the EPOCh/EPOXI mission that has been reorganized by MAST to group data by target (the Earth and 8 stars: GJ436, HAT-P-4, HAT-P-7, TrES-3, TrES-2, WASP-3, XO-2 and XO-3) and by visit.  Most MAST users will find this organization of the data easiest to use, but frequent users of the Planetary Data System (PDS) might prefer the version identical to the PDS that includes PDS annotations. See the respective README files below for more information.
