I put the one with the sol on my iGoogle page (thanks!). It matches mars time on my computer to within ~1 sec (using my own system clock I assume). That matches time displayed in the SOC to <15 sec. Mine's right ;^) Unless you believe Einstein, then there's a 15 minute light-time ambiguity. That ambiguity is really annoying ... so I choose not to believe in Einstein. |

Mark/Deimos,
Enjoyed your talk on today's press conference, however I rapidly became lost keeping track of the various reservations for the robotic arm workspace and wondered whether you might be able to put together a map overlay highlighting the trough between the polygons and the various designated preserves/workspaces. |

Can someone explain to me why some of the SSI images taken through different filters don't have the same pointing? The difference doesn't seem to be reflected in the metadata info imbedded in the images either, so I'm finding it all but impossible to correct for it automatically in my processing software.
Cheers, James -------------------- |

I wondered about the same thing, James. Could it be due to filter optical characteristics? I'm reminded of a very similar thing with Cassini's WAC, the RGB filters are consistently offset up to 3 pixels from each other's boresight.

Perhaps the wind is moving the SSI slightly in between images?

I don't think it can be optical characteristics as some images have the shift and some don't, it is very inconsistent as far as I can see.
EDIT: On further investigation it looks like the shift between the 1,B and C filters in the 3 problem frames in the sol 6 mosaic I posted in the other thread is approximately the same in each of them. But why are the other 5 fine? I'm confused! -------------------- |

But why are the other 5 fine? I'm confused! Working that. There is a zone where elevation backlash is acting unstable. I have an idea what to do, but in terms of getting new diagnostics up there are still bigger fish to fry, so it may be a little while. |

Informative blog entry by Mark Lemmon
discussing why taking pictures with a robot on Mars isn't exactly point and shoot. Mark, when you get the opportunity I'd be grateful for more detail on why and how Phoenix imaging operations are different from working with the MERs. Also liked the discussion of why the title was appropriate. TTT |

Thanks for the reply Mark, I guess I'll work on my own fix to realign the images in the meantime.
