I found out something specific about the ancient items and how they relate to the obelisks this evening.
First of all I went through all 27 permutations of items you can carry in the SRV and scanned all 15 active obelisks, recording the response on a grid.
Then I double checked it (yeah, I really did the circuit 54 times in 2 evenings!).
I'm broadly finding my results are similar to others, however because of the way I've got my permutations listed I noticed a pattern in the data.
I was recording where I scanned a Guardian data packet, whether I got a message of failure from Ram Tah, or
no message at all. (Any mistakes in the sheet aren't intentional)

And that was when it jumped out at me that 4 of the 6 items "unlock" a group of obelisks so that they don't report a failed scan attempt.
A big jump out is that
Relic with
Totem doesn't work on
ANY of the 15 obelisks that we know are active.
