Not an answer...
rather a tip on finding anything in the system that you have capacity to change.
For example, Kstars has a number of cities preinstalled. However, my house in rural Mexico is at least a minute away from the closest city. Yes, it makes no sense to worry about my ability to visually detect one minutes difference in star position when I am barely able to find the North Star. However, we Linux folks do a lot of things 'just cause'. So I took the GPS reading from my cistern, and entered it.
Later, I realized I had typed a number wrong and there is no uninstall in Kstars, at least not in that version.
Since the town name is not well known, I typed the following command:
grep -EHRs weirdcityname /
I hope that is correct, it looked through every system file for that unique city name, and finally reported where it was. I went there and edited that file to the correct numbers. It was in a really weird place, that I would never have looked at. I now have it added to my permanent list of files that I need to back up when I reinstall or install a new distro.
Just so can you find that sort of thing, if what you seek is uncommon. I have in some cases input a name ZZXXYY in an input box or some unique letter combo, and it finds that file.
