Wrote code to process+stitch the raw EDR files from MRO HiRISE's imaging of 3I/ATLAS into a mosaic. It seems to mostly work using example data from Mars surface data but looks completely messed up when used on the 3I/ATLAS data. Guessing I'm not accounting for exposure time? Left: Mars Right: 3I

Wish we could've gotten tighter constraints on the nucleus

It's still cool that they got a photo of a fast moving comet from the orbit of another planet but slightly discouraging that the size couldn't be constrained

Seems odd that NASA has released only a 37 kilobyte jpeg photo of 3I/ATLAS from HiRISE instead of a raw image

He seems to be talking about the ion tail because he mentions what he's measuring isn't seen with the R-band filter. Wouldn't it seem a little too ridiculous for him not to know the difference?

Doesn't this imply he's talking about the ion tail and not the dusty tail? It wouldn't seem believable that he's not aware of the two distinct types of tails and the forces acting on them.
