Additional information

This analysis makes use of much of the data that I obtained as member of the Supernova Cosmology Project (SCP) and the Supernova Legacy Survey (SNLS). Specifically I was responsible for obtaining and analysing many of the spectral observations in the SCP sample, and was PI of the Gemini program for spectroscopic observations of the SNLS sample used in this analysis (originally published elsewhere). These spectral observations are used to determine the redshifts and to confirm the type of SNe, both essential ingredients in the analysis of Supernovae for cosmology. I provided comments on various drafts.
