Hi Dave, Finally, finally...you'll find a new version of the paper at http://www.ast.cam.ac.uk/~cclarke/. I've tried to correct the typos, spellings etc, put inmore recent references and analysed the mode structure a bit. I held back on submitting the last version because I wanted input from the galaxies discussion group a few weeks back. actually I didn't get much on this paper - more useful was the fact that Eve Ostriker was there and said she is involved in a large observational programme looking for offsets. She cautioned though that K band isn't such a good tracer of mass as we had hoped... I bet this all seems incredibly distant... Btw I've asked Hardip to extend the lifetime of your account until we get a referee's report. Do take a look and If it's okay, I'll submit it early next week. Hope life's treating you well, All the best, Cathie
