Surface brightness bias in galaxy catalogues: distance effects

, 1993
We have investigated the apparent variation of the surface brightness distribution of disc galaxies with distance within three different samples 1) a diameter limited sample of ESO catalogue galaxies in the direction of the cluster A3574 in Centaurus ...

Brightness-Temperature Retrieval Methods in Synthetic Aperture Radiometers [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2009
Bightness-temperature retrieval techniques for synthetic aperture radiometers are reviewed. Three different approaches to combine measured visibility and antenna temperatures, along with instrument characterization data, into a general equation to invert are presented.
