well, yes and no. the number may not be much different, but, if they are doing this in the image domain as well as line of sight, it shows that progress can be made in 3D. that is, if the result is believable? I would assume so, given they are presenting in public, but need to see paper. and maybe they are focusing on LoS PS? mantra: 'multiple approaches and experiments are good...'
I will be talking about PAPER and HERA at New Mexico Tech physics dept today at 4PM, for those in ABQ who might be bored and want to take the drive...
