Beginning of ReadMe : J/MNRAS/389/1871 Type Ia supernovae candidates from SDSS (Horesh+, 2008) ================================================================================ The rate of Type Ia supernovae at z 0.2 from SDSS-I overlapping fields. Horesh A., Poznanski D., Ofek E.O., Maoz D. <Mon. Not. R. Astron. Soc., 389, 1871-1880 (2008)> =2008MNRAS.389.1871H ================================================================================ ADC_Keywords: Surveys ; Supernovae ; Photometry, SDSS Keywords: surveys - supernovae: general - cosmology: observations Abstract: In the course of the Sloan Digital Sky Survey (SDSS-I), a large fraction of the surveyed area was observed more than once due to field tiling overlap, usually at different epochs. We utilize some of these data to perform a supernova (SN) survey at a mean redshift of z=0.2. Our archival search, in  5 per cent of the SDSS-I overlap area, produces 29 SN candidates clearly associated with host galaxies. Using the Bayesian photometric classification algorithm of Poznanski et al. (2002PASP..114..833P), and correcting for classification bias, we find 17 of the 29 candidates are likely Type Ia SNe.
