The answers they get will be something like
probable amplitudes for waves from specific
sources and can be compared against known
objects in those locations

The data is what it is. The algorithms used
can and will be reviewed. It is also possible
that the data will be independently reprocessed
as Markwardt did for the Anderson data on Pioneer
Those who exaggerate tend to get found out.
