Looking into this more, I’ve concluded it is really an upstream issue: https://github.com/numpy/numpy/issues/13929

@pllim - this warning was meant to show only when we are actually trying to write to a broadcast array - which we should never do. So, I think we should only look at the actual cases where the warning is given.

From the log file, it looks like there is only a single problem somewhere in the LombScargle implementation, which we probably can fix by looking carefully at that code.
