I am trying to track down the location of Hyperion features listed on the Planetary Names website

http://planetarynames.wr.usgs.gov/jsp/Feat...=Stat&show=Orig

I've been able to track down a map of Hyperion with some features names:

http://www.etsimo.uniovi.es/solar/r/sat/hyperionmap.jpg

but it doesn't have the crater called Helios. Even using the lat/lons on the feature list won't help since the craters the map does have don't correlate with the lat/lons for those crater in the list. Any help on trying to confirm the identities of these craters and identifying Helios would be helpful.

Volcanopele: I made that map 5 years ago, it is based on Phil Stooke's shape model and although I don't remember exactly I placed the names according to a figure in Peter Thomas' article, that's why it does not include Helios and lat-long may be different from IAU list.
