I noticed this strange name for a CUDA50 WU on my computer. Never seen this before. What is the meaning of the "guppi" and "MESSIER" parts in the file name?

Just watched it while the WU was processed. Took 3 seconds only.

Curious about where HIP62472 is located?

I use stellarium, free to use, just put HIP62472 in the search window and

it takes you for a ride may have to get rid of the ground and atmosphere.

then use the mouse, scroll to zoom in on the object, which seems to be

a double star HIP62472A and HIP62472B

just a fyi

PS it also works for those Messy names like MESSIER031 although it likes M 31 better

Any triplet scores perhaps?

Checking the logs, I do find a triplet of 24.06 from a WU which had 9 more lines as well in the triplets table in SMV, all having a power or score of 19.87.

But assumedly you are not supposed to associate or relate such a triplet score with being something else.

Here we most likely are still left to be guessing.
