Which 16 are these? I can find documents on-line with coordinates for 64 location, (sometimes numbered 1 through 64, but not here), but I can't figure out which 16 are used to produce this image.
I found images of KAT-7 and MeerKAT in google maps - maybe someday we can get daily ground truth updates from Planet Labs, but for right now I'll stick to stackexchange.
Image from the press release:
Above: MeerKAT array core from Google Maps at (30.7136109S, 21.4399576E). The remaining sites are farther away and can be seen if one zooms out.
