Ask HN: Askap Dataset in Steradians/Pixel

Can someone figure out the pixel size of the new ASKAP dataset ("which covers 83% of the sky, is a combination of 903 individual images, each containing 70 billion pixels" [1]) in steradians [2] as well as for the Hubble Ultra Deep Field, as I am curious how to know their relative resolutions in steradians/pixel. (Approximation using the above values may not apply to actual dataset if steradians ranges across the images like areas delimited by latitudes/longitudes.) Can hardly wait for the app to explore this
