Hi Ving,
Thanks for that - all I need now is for this cloud to go away - which seems to have settled in for the long haul!
One newbie question : You mention the difference between true binaries and optical doubles - could you classify which category each of these fall into?
I became interested in binaries a month or so ago and would look forward to more of these lists - but I'd love it if any future lists could show which ones are 'real' binaries. They seem much more interesting to me (just my opinion).
