Query: The Intrinsic Properties of SDSS Galaxies   The observed properties of galaxies vary with inclination; for most
applications we would rather have properties that are independent of
inclination, intrinsic properties. One way to determine inclination corrections
is to consider a large sample of galaxies, study how the observed properties of
these galaxies depend on inclination and then remove this dependence to recover
the intrinsic properties. We perform such an analysis for galaxies selected
from the Sloan Digital Sky Survey which have been matched to galaxies from the
Two-Micron All Sky Survey. We determine inclination corrections for these
galaxies as a function of galaxy luminosity and Sersic index. In the g-band
these corrections reach as as high as 1.2 mag and have a median value of 0.3
mag for all galaxies in our sample. We find that the corrections show little
dependence on galaxy luminosity, except in the $u$ band, but are strongly
dependent on galaxy Sersic index.
  We find that the ratio of red-to-blue galaxies changes from 1:1 to 1:2 when
going from observed to intrinsic colors for galaxies in the range -22.75 < M_K
< -17.75. We also discuss how survey completeness and photometric redshifts
should be determined when taking into account that observed and intrinsic
properties differ. Finally, we examine whether previous determinations of
stellar mass give an intrinsic quantity or one that depends on galaxy
inclination.
