sol 13 RAC 13:37-13:57 RGB-D sequence of ???:

Not a clue.
I have rotated the images 180 degrees in the belief that the sequence is under the lander, since the pointing direction is elevation -45.211 azimuth 211.397.
er, Dana, I regard any magnification over 2X as dangerous -- even with original 12 bit uncompressed data. 4X of 8 bit lossy JPG is folly.
If you must go there, download the full resolution TIFF versions of the images from the Nasa Photojournal site and work with those.
Here is an example mixing the official TIF images with some of my 2X JPG work. ( The first and last image were originally full resolution TIF images from the site )
Maybe someday they will post 16 bit TIF versions ( 48 bits color ) of their products.
Yeah - right.
