Tony,

Thanks for the summary. It would be good to get a more detailed news 
item on the BAA website with the links you mention. I'll do this once I 
have your material. Thanks also for pointing people to the BAA material.

Regarding the cal frames do they really want everything? My flats, darks 
etc. are usually median stacks of a hundred frames or so. Do they want 
everything or just the actual stacked cal frames used.

Also, most of my 67P images are stacks of lots of short (60s) exposures. 
Do they want all the raw sub-frames as well as the calibrated stack or 
do they want calibrated subframes?

I can understand why they might want all of the original data but that 
means that there will be an awfully large number of files to upload and 
I'm not sure that the mandated naming system would work for so many files.

Nick.
