And yes, this is one way of representing the data. I'm not sure exactly what your question is though, as actually getting this data is really important to confirm a variety of theories and also to potentially open up new avenues for investigation. And this cost orders of magnitude less than Hubble, whose purpose was also to generate photographs, seeing as how they simply connected together existing radio telescopes.
The point was to demonstrate that this technique is feasible. Now they can use it to image all sorts of other stuff and learn lots more.
So a photograph.
Is it wrong to say this is a logical improvement, extension of radio interferometry?
Or gather data that will help us study blackholes?
Because the press is largely focusing on the picture and not telling much else detail.
And is Boumans contributions to do with the making of this image?
As I understand it, the notability of the project is that it found a novel way to process data from coordinated data collectors scattered around the earth into a single coherent data set (with more resolution than any single collector could gather).
