Despite obtaining convincing early results using both HawkRAO code and professional analysis applications, wider and more detailed analysis has revealed these to be almost certainly terrestrial RFI.
I am now of the opinion that - as far as HawkRAO observations are concerned - that merely finding dispersed transients with characteristics which closely match those of target cosmic objects is not sufficient evidence of cosmic origin.
Also - the argument that the transient covers a large proportion - or all - of the bandwidth is (IMHO) also not sufficient.
Professional radio astronomers refer to the danger of single receiver observations - noting that many instances where terrestrial transients have been wrongly assigned to being of cosmic origin.
A presentation made by a leading expert in transient radio astronomy made the following points under the heading...
"How to Tell if FRBs are Real or Not?"
Single receiver dishes:
can’t tell difference between a “Peryton” and an “FRB”
Multi-element receivers:
hopefully multiple-beam detections = microwave
single beam detections = FRB?
Detect with an interferometer:
ascertains D > Fresnel Scale
Detect at two sites at the same time
Get one that repeats
Based on my own experience here at HawkRAO I agree 100% with these points.
