Hey Malcolm and Barry,
Thanks for your explanatory notes!
I am sure I am not alone amongst optical astronomers in finding radio astronomical equipment to be slightly confusing. Just making interferometric radio observations of a single object seems to me to be a difficult and extremely complex and very-time-consuming task, making even an imaging run with a Very Large Optical Telescope seem simple in comparison.
I also have trouble with intuitively conceptualizing frequency;
like most optical astronomers, I do have a real gut feeling for "so many nanometers" or "so many microns" in wavelength, but my mind starts to reel when people talk about GHz and MHz !
cheers,
Robert
