There are enough people in the Ifeffit-using community who are SSRL
users and who might be interested in this question.  SO I am CCing my
answer to the mailing list.

Question 3 at this FAQ page:
explains in some detail what kind of data Athena is able to read.
Obviously SSRL's binary format cannot be imported without the use of a

It would be possible, in principle, to write a plugin that is capable
of reading the SSRL binary format.  However, to my knowledge (which
certainly may be faulty) the technical details of the SSRL format are
not published any place where I can find them.  That's something of an
impediment. ;-)

It would most certainly help to convert to an ascii format.  Not
having worked at SSRL since my grad school days, I don't really know
how to do so.  Your beamline scientist should be able to help you with
that.  Perhaps someone on the list will know the details.
