Show me where they discuss sources of error - as a paper it's poorly written, I mean what kind of academic whacks this into an abstract and decides it's OK.
"We present a broad range of UAPs. We see them everywhere."
Everywhere? In the cupboard at home? In the local movie theatre?
Nowhere they discuss sources of error - it's a description of their setup, and then a straight dive into here's a taxonomy of all the UAPs. Plus, there's not enough there to reproduce their rig if indeed UAPs are "everywhere".
