About the APXS map. Here it is, superimposed on the earlier ISRO map. There are multiple points of disagreement. We can say that the definitive map is not yet available. One thing that will help will be a post-mission OHRC image which might show the rover and clarify its location. The lander location is more accurate on the APXS map.

Shan Subramanian has tweeted this LRO image:
https://twitter.com/Ramanean/status/1750895541045915669 I compared it with the OHRC image used as a background to the rover traverse map. There seems to be a feature casting a shadow like the lander but smaller and not present in older images. It is close to where the previous maps placed Pragyan so it is probably the rover.

IAU approves ‘Statio Shiv Shakti’ as name for Vikram-2 landing site.
https://planetarynames.wr.usgs.gov/Feature/16272 QUOTE Compound word from Indian mythology that depicts the masculine (“Shiva”) and feminine (“Shakti”) duality of nature; Landing site of Chandrayaan-3’s Vikram lander.

This link shows a new OHRC image of Chandrayaan 3's Vikram lander and a small spot next to it. The post suggests it is Pragyan, the rover, right next to the lander. But if you follow the source you find an Indian media report on this specific image which says it was taken on 15 March 2024, i.e. long after the end of the mission. ISRO's map of the traverse shows that Pragyan stopped operating about 33 m northwest of the lander (and a second map from one of the instrument PIs puts it in a similar location). This new image actually shows the long shadow cast by Pragyan's solar panel, parallel to the lander's shadow, in that location. So the second little bright spot cannot be Pragyan. Curiously, the latest OHRC image of SLIM shows a similar bright spot near the lander, not corresponding to anything obvious. I think it may be an artifact, caused by some internal reflection of the lander image perhaps, and showing up just because it is so bright.

How much do the OHRC images of the Apollo descent stages constrain that hypothesis? I don't see anything like this in those images but I can think of a few reasons why.
1) The descent stages are so large that the artifact is overlapping with some hardware in the image? 2) The descent stages are covered in enough dust to reduce their reflectivity enough to cause this phenomenon? -------------------- -- Hungry4info (Sirius_Alpha)

I don't know but my guess may be wrong! I am still puzzled by the presence of a bright spot adjacent to each of two landers. The shadow cast by Vikram looks like it comes from both bright spots, so the two spots might be from different parts of the lander, but SLIM is still a puzzle.

We have another Chandrayaan-2 image of the lander, taken on 25 April.
