Looter Lord Elgin presented an Italian "translation" of a fictional Ottoman firman, the original of which no one ever saw or had otherwise knowledge of, then ripped off the #ParthenonSculptures, sawing some in his haste, and moved them to England, where they were scraped clean of the ancient colors that still remained on the marbles.
Turkiye's statement that they "are not aware of any document that legitimizes that «purchase» done by coloni[al] #UK back at that time"
The temple was first destroyed by Theodosius' bigoted Christians in the 4th c CE, then by Venusian Francesco Morosini in the 17th c, who described his vandalism as "a fortunate shot" and went on smashing sculptures from the pediment in his attempt to loot the Acropolis, and then in the early 19th c by Lord Elgin, who stole about half of the sculptures that had survived 2000 years on the Sacred Rock.

The odds are better for a Martian Crow to flyby the heli and say "caw-caw" than they are for the rover to cross the sand field and say "cling-cling" 🥴
On Sol 1168 the rover moved to RMC 52.5032 across the ancient riverbed and stopped a few meters away from a light colored layer of rock at the foot of the northern bank, which appears to be the same layer with that of Bright Angel.
¹"the bacon strip": unofficial name for a light colored layer of rock back at the Three Forks area.
The HiRISE/USGS imagery has been imported into QGIS and since forgotten. I'm not fiddling with the rest of the imagery any more, though I used to do that earlier in this mission.
"Space economy" seems to have real impact on the way NASA engages with the public. I've spent a lot of time creating workflows with their data, e.g. for the #MarsWeather reports, LA, etc, but they're now discontinuing services while the mission is still active. That's not very encouraging.
Soon the telescope platform at ESO's Paranal Observatory in #Chile will look very different at night: all four of the 8.2 m telescopes of the VLT will be equipped with lasers! This is one of the ongoing upgrades of the GRAVITY+ instrument, which will allow us to study black holes, stars and planets like never before.

You are welcome. About what processing I've done to them: I kept some notes at the time (about a year ago, maybe?), which were supposed to have been saved along with the rest of Mars2020 stuff, but I can't find them rn. Those flats were very obviously different from the rest of SUPERCAM's images and I immediately tried them as flats, but I can't recall whether those I'm using now are the EBY or the ECM.
LA is not capable of such kind of searches, so I may have to sift through them

Have a look at the SUPERCAM images from Sol 868, they were about a year ago and possibly the ones I uploaded to my repository. The ones I uploaded are value-stretched to cover 100% of the high (bright) range.
@stim3on
I see you have de-saturated the skyflats. I use them as is, with their cyan-ish color in place, which apparently when dividing an image with them, removes the green cast.
I just did the procedure again from scratch with the EBY png directly downloaded from NASA, did some white balancing to my taste, contrast stretched it, and here it is:
@stim3on
Yes, I noticed you mentioned that earlier. But you employ that optimized debayering technique, IIRC, that makes your results better than those of NASA, judging by the outcome. I'm using G'MIC for debayering, and I don't trust my settings will give better results than NASA's, tbh.
@stim3on
That looks very good, not even a hint of the green cast, and flatter than my quick and dirty one I posted earlier. I can get better vignette correction, but then I too need to correct the perimeter on a separate step by using masks.
@stim3on
Oooh! Extra flat results! I need to see how I can include this into my handy workflow without becoming an expert in juggling pixels around with math 😜. I tried that in the past and it's fascinating, but I expect to only live to be 105 yo, so I can only do so much in this life 😆
Thanks for the link!
