Caption: Figure 2.

Histograms comparing the set of all spectroscopically confirmed SNe Ia against the subset that is deemed cosmologically useful. Filled bars indicate the full spectroscopic sample of ﹩365﹩ SNe Ia, while outlined bars indicate the ﹩279﹩ used for our cosmology analysis. Top: distribution of redshift. Middle: distribution of radial angular distance from center of focal plane. Bottom: distribution of the age at discovery as determined from the date of peak brightness subtracted from the discovery date.
