Refined position angle measurements for galaxies of the SDSS Stripe 82
  co-added dataset
  Position angle measurements of Sloan Digital Sky Survey (SDSS) galaxies, as
measured by the surface brightness profile fitting code of the SDSS photometric
pipeline (Lupton 2001), are known to be strongly biased, especially in the case
of almost face-on and highly inclined galaxies. To address this issue we
developed a reliable algorithm which determines position angles by means of
isophote fitting. In this paper we present our algorithm and a catalogue of
position angles for 26397 SDSS galaxies taken from the deep co-added Stripe 82
(equatorial stripe) images.
