Artifacts within stars

Post by Rkonrad »

I did a presentation on StarTools at my local rasc astronomy group a couple of nights ago and got a weird artifact after I applied colour just before disengaging tracking. The video is rather long but if you queue to 1 hour 50 min, you should see. I was using the most recent version of 1.6 64 bit with a windows computer.

Thanks!

Hmmm... Any chance you could post a link to the video or perhaps a screencap?
Thank you!

Many thanks! Definitely looks odd and I don't have a quick explanation for this. I haven't seen this before, nor do I have a way to replicate this :(
Any chance you could share the dataset with me so I can try to replicate this? Thank you!

Really appreciate it.
I followed along with the video and managed to reproduce the issue.
It's likely a rounding error issue in the Bin module that may see some values become out of bounds (e.g. over-exposed star cores). The unfortunate module immediately run after it, will have to be able to cope with the rounding errors (which is not always the case).
It should be fixed in the next version - thank you for reporting this!
