Hi Arati, If you'd like to drop me an email with a specific BBC contact query, I'll do what i can to help. I'll need details though, about who you are, what you want, and who you'd like to talk to. This is a big organisation, and it's not always easy to put the right people in touch,

Which is why we have roughly the range we get; why we have such a near perfect 1/sigma callibration curve and why the range of values you get it so odd - and why they filter certain types of noise so badly. > >And perhaps, perhaps: > >5.

Anyone here with a good high-res SRL which can do enough IR detection to check if indeed this is the case ? I guess a fun test would be to use a mirror to project a few extra pixels onto a flat area - and see if that area suddenly jumps 'forward'. > >Thanks, > >Dw > > >0: http://www.wired.co.uk/magazine/archive/2010/11/features/the-game-changer and all the mystification on how they work. >1:http://www.zimbio.com/Popular+Topics+in+Astronomy/articles/vnjstT2fTM2/Green+30mw+Laser+Pointer+Pen+Style+Star+Holographic >- >Sent via the backstage.bbc.co.uk discussion group.
