Inclination-Dependent Extinction Effects in Disk Galaxies in the Sloan Digital Sky Survey

We analyze the r-band absolute magnitude and u − r color of low-redshift (z 0.9) to ~0.26 for nearly edge-on galaxies (q < 0.3). When the dimming law ΔM_r ⍺ (log q)^2 is used to create an inclination-corrected sample of bright exponential galaxies, their apparent shapes are consistent with a distribution of mildly noncircular disks, with median short-to-long axis ratio γ approx 0.22 and median disk ellipticity ε approx 0.08
