[fitsbits] Viewing .fts flies

[Jimmybobs at gmail.com]

I've got a load of .fts files (from the SOHO archive) that I need to
study, but I'm having trouble finding a viewer that will open them.
When I searched for .fts programs online, it always gave me .fits
programs- is this right? Are they the same? I've been trying to use a
program called ds9, but to no avail. It might just be me doing
something silly, but can anyone point mein the right direction? Thanks!
