Rob Manning and I swopped emails last night - and we think it might make sense to pool all the questions people have about MSL (and specifically MSL's EDL ) into one thread - and then answer as many as make sense either via a Q'n'A in the style of the previous ones I've done with Steve and Jim - or via Rob's typing fingers.
It'll be a few weeks till we sort this out - but submit-away until then ![]() Doug |

Here's one for you Mike - I get bayer filters - and I get the normal way of doing filtered obs. How do you set up a CCD to do single shot colour but ALSO do filtered obs as well? Is it like a hybrid bayer filter that has an R, a B but only one G with what would be the 'other' G as a clear for use with filters? (That's a complete and utter guess)

(That's a complete and utter guess) That might work well, but we use an off-the-shelf sensor so we can't have a custom filter. No, the narrowband filters work because the Bayer filters are transparent in the near-IR, where the narrowband color can be used to look for iron-bearing minerals. In the visible, there is always some overlap between the narrowband filter and at least one of the three Bayer filters, often two. In those cases we just adjust the interpolation appropriately to use only the pixels that have usable signal after light has passed through both the Bayer and narrowband filters. -------------------- Disclaimer: This post is based on public information only.
