Heavenly Mechanics

Measure coordinates with the astrolabe at five locations near the Isle of Singing Water and the Irdrich shore. Return to Yasskul Naboo with the results.

So, Igor Kalinin sent you? And may I ask what the Committee requires of me? Just help? Pardon me if I don't believe it. I have an assistant to lug equipment from place to place and you cannot make the required calculations anyway. Well, if Kalinin wants to send his own trusted man to monitor my research, so be it. But know this: since you are now my assistant, I will not give you any slack!
That idiot I sent to measure coordinates with the astrolabe went missing, while data is needed right now. So, assistant, here is the astrolabe and a marked up map where you need to record measurements. Taking measurements is simple: stand in the indicated spot, guide the astrolabe pointer to the most outstanding reference point, say Giant's Claw, look through the viewer and record the number that you see. As I said - simple!
That's all. Now go, record measurements, and come back soon. We still have many things to do!

I need this information to compare the coordinates I know with the entrance coordinates of the wormhole. I can then draw a certain conclusion whether there are any differences or not.

Aha, there are the coordinates. Let's see now...
How odd! The data do not match any of my theories! Such disposition is simply impossible.
Were the coordinates accurately recorded? Do you guarantee that there are no errors? Hmm... Very well, let's try to correlate data...
