The SuperNova Legacy Survey: Measurement of cosmological parameters from the First Year Data Set.
J. Guy, on behalf of the SNLS collaboration

We present the distance measurements of 72 high redshift type Ia, supernovae discovered during the the first year of the SuperNova Legacy Survey. , All steps of the analysis from the differential photometry performed on Elixir detrended images , to the estimation of cosmological parameters are described. , The systematic error budget is detailed.
