IBEX-Lo maps in PNG display format every 6 months

ResourceID

spase://NASA/DisplayData/IBEX/Lo/Maps-PNG

Description

Hydrogen ENA fluxes in each of three IBEX-Lo energy bands in each of 21,600 [720(longitude) by 30(latitude)] bins, accumulated over 6 months. Bins are defined in J2000 ecliptic coordinates. Maps are available for energy bands 5 (209 eV), 6 (439 eV), and 7 (872 eV). PNG-formatted image files are 24 KB in size. Digital versions of these images in txt format are identified by VEPO as a separate data product.
