VizieR Online Data Catalog: Stellar masses and rest-frame u-g colors of SNIa (Jones+, 2018)

For this analysis, we combine 216 z<0.1 SNe from the Pantheon compilation (Scolnic+ 2018ApJ...859..101S) with 178 SNe Ia from the Foundation first data release (DR1; Foley+ 2018MNRAS.475..193F).

We measure host galaxy properties with photometry from the PS1 first data release (Chambers+ 2016, II/349) and the Sloan Digital Sky Survey Data Release 14 (SDSS DR14; Abolfathi+ 2018ApJS..235...42A).

After all cuts, grizy images for measuring the local mass step are available for 273 SNe Ia. Of these SNe, 195 lie in the SDSS footprint and therefore have u measurements for measuring the rest-frame u-g color.
