Image Annotation Script: Same image, Different results on different computers

[Josh Lake]

I am going to work with some students on identifying and calculating distances to HIP stars, stars in the Hipparcos catalog.

On two different computers, I ran Image Solver on the same image and it pulled in the same results for the parameters of the field.

One one computer, Image Annotation v1.8 produces a few dozen Hipparcos stars with that catalog loaded.

On another computer, seemingly with the exact same image with same parameters, it only annotates two stars.

Any idea on what's causing this?

Thanks for any help!


EDIT: As I fully expected to happen, the very instant I posted this, a solution popped up. I added a '20' to the minimum magnitude option and re-ran it. Tons of HIP stars! Then I tried other values and it also worked, getting fewer stars for brighter magnitudes. When I leave it blank, I still only get 2, unlike my other computer.

So it's fixed in my book, but I still don't understand why it happened. I should be able to leave those options blank and it'll still work.

Anyway, thanks Andres for the great script, I've always loved this one.

Hi Josh,

I've never seen that behavior.

Perhaps in one of the computers the query to the server had problems. Since the script caches the queries the same invalid result keeps appearing every time you try the same parameters. If this is the case, the button "Clear cache" should fix the problem. You can also try resetting the Javascript engine (Open the  Script Editor window and select the menu "Execute | Reset Javascript Runtime").

Will do! Thanks again for the script. It was just so odd -- a new installation of PI on that second machine but it only pulled up 2 HIP stars.
