Potential Bug Affecting Pi 3 Stations reports

[shlometeor]

I think I may have found a bug, and I wonder if it affects many older stations with Pi 3. I also noticed that the older Pi 3 stations cannot run the ML filtering for better second detection, but the bug I observed occurs during the detection process, not in post-processing.

Details:

•	Station: IL0001 (a020d3 revision code corresponds to a Raspberry Pi 3 Model B+)

•	Issue: The same meteor appears to be duplicated in consecutive FF FITS files, e.g.:

•	FF_IL0001_20240908_204153_361_0340224.fits

•	FF_IL0001_20240908_204213_881_0340480.fits

•	Observation: In CMN_binViewer, the backgrounds are not exactly the same, but the same meteor is present in both files and is reported twice.

I've attached both fits files to this message.

Here is the log around the creation of both files:
