Ca II and Na I Quasar Absorption-line Systems in an Emission-selected Sample of SDSS DR7 Galaxy/Quasar Projections. I. Sample Selection

Authors: B. Cherinka and R. E. Schulte-Ladbeck

Caption: Figure 1.

Shown here are the redshift distributions for the parent galaxy and quasar sample. As expected given our catalog constraints, the distribution of quasars does indeed lie behind the distribution of galaxies. The inset plot shows a zoomed region of z < 0.5.
