Abstract:
Disc central surface brightness for 30000 galaxies from the Sloan
Digitized Sky Survey (SDSS) Data Release 7, in the r-band. Virtual
Observatory methods and tools were used to define, retrieve and
analyze the images for this unprecedentedly large sample classified as
spiral galaxies in the LEDA catalogue.
These parameters are also available for all other SDSS bands
(u,g,i,z), and they can be retrieved from the Author.
