`align` not returning mount back to exact start position #278

bgottula commented 1 year ago

After recent upgrades of my machine to Mint 21.1, align is not returning the mount back to the exact starting position by the end. I ran the program at least three times, and in every case the RA axis seemed about 10 or so degrees off of vertical, with the tube tilted left and counterweights tilted right. DEC seemed about right though. Not a huge deal, but strange and unexpected.

Curiously, the fix I found for #276 (changing the dtype of the distance matrix to int) seems to eliminate this problem. In one test I've run with that fix returned the mount very close to the initial position. I'm not sure why these two things are related.
