Hello,
Apologies if this question has already been asked – so far I haven’t been able to find any similar posts with targeted keyword searches.
I’m currently an undergraduate intern at an observatory and I rely on AIJ to reduce data and generate light curves, and unfortunately, I can’t carry out that work all the way until I resolve this issue, so any help would be much appreciated!
The issue happens when I attempt to track moving targets using multi aperture photometry; when I tried to let the program track an asteroid automatically, the aperture did not follow the asteroid but instead remained stationary. When I tried to manually track with single-step mode, the red reference star apertures moved with the green target aperture.
I tried deleting and reinstalling the application multiple times and making sure all files were in the same folder, restarted my computer, and looked up the issue online, but have not been able to resolve it yet.
After all that, it now doesn't seem to do any tracking at all -- when I try automatic tracking all of the windows pop up but nothing actually happens, and when I try single-step mode, the log says I have what appears to be a Java-related error.

I’m not sure if this is an AIJ issue or an issue with my device specifically (I’m using a Windows Surface Pro 9) but I’m hoping that someone here may have seen this before and will have some insight. For some additional context, I don't believe I had Java downloaded on my device before I got AIJ, so I downloaded the version of AIJ for windows that comes with Java. Admittedly I am not very tech-savvy, so this may be an easily-fixable error that I don't yet have the skill/experience to recognize and resolve by myself.
Thanks so much!
Best,
Erin
