Beginning of ReadMe : J/MNRAS/430/1746 90 new SNIa from SDSS DR7 (Graur+, 2013) ================================================================================ Discovery of 90 Type Ia supernovae among 700 000 Sloan spectra: the Type Ia supernova rate versus galaxy mass and star formation rate at redshift  0.1. Graur O., Maoz D. <Mon. Not. R. Astron. Soc., 430, 1746-1763 (2013)> =2013MNRAS.430.1746G ================================================================================ ADC_Keywords: Supernovae ; Redshifts ; Photometry, SDSS Keywords: methods: observational - surveys - supernovae: general Abstract: Using a method to discover and classify supernovae (SNe) in galaxy spectra, we find 90 Type Ia SNe (SNe Ia) and 10 Type II SNe among the  700000 galaxy spectra in the Sloan Digital Sky Survey Data Release 7 that have star-formation histories (SFHs) derived with the VErsatile SPectral Analysis code (VESPA). We use the SN Ia sample to measure SN Ia rates per unit stellar mass. Description: For the purpose of this work, we used the 776447 galaxy spectra in SDSS DR7 that have SFHs obtained by Tojeiro et al. (2009, Cat. J/ApJS/185/1) using the VErsatile SPectral Analysis code (VESPA, Tojeiro et al., 2007MNRAS.381.1252T)
