VizieR Online Data Catalog: The supernovae Ia Pantheon sample (Scolnic+, 2018)

This analysis relies heavily on the work by Rest+ (2014, J/ApJ/795/44) and Scolnic+ (2014ApJ...795...45S), hereafter R14 and S14, respectively. R14 and S14 analyzed the first 1.5yr of PS1 SN Ia data and combined it with a compilation of low-z surveys. The SNe Ia presented in this paper include all SNe discovered during the PS1 survey (2009 September-2014 January) that have been spectroscopically confirmed as SNe Ia.

The PS1 data presented here are from the PS1 Medium Deep (MD) Survey, which observes SNe in griz_p1 with an average cadence of 7 days per filter. The spectroscopic selection over the full survey is similar to that outlined in R14. Spectroscopic observations of PS1 targets were obtained with a variety of instruments: the Blue Channel Spectrograph and Hectospec on the 6.5m MMT, the Gemini Multi-Object Spectrographs (GMOS) on both Gemini North and South, the Low Dispersion Survey Spectrograph-3 (LDSS323) and the Magellan Echellette (MagE) on the 6.5m Magellan Clay telescope, the Inamori-Magellan Areal Camera and Spectrograph (IMACS) on the 6.5m Magellan Baade telescope, the ISIS spectrograph on the WHT, and DEIMOS on the 10m Keck telescope. A table of the spectroscopically confirmed SNe Ia that includes the dates of the observations and the telescopes used is given in Appendix A (see Table 15 and spec.dat file).
