SUMMARY:Toward 3D Spectra of Galaxies: Extinction from Inclination-depende

DESCRIPTION:Galaxies are oriented at various viewing angles and located at
  different distances from us\, large samples of fiber-fed spectra from sky
  surveys therefore contain spatial information about the galaxies. Careful
  sample selection in avoiding biases should allow us to re-construct stati
 stically galaxy spectra in 3D. Here I present the inclination dependency i
 n composite spectra of star-forming disk galaxies from the Sloan Digital S
 ky Survey. I discuss what we learnt about extinction in the galaxies.
