Values of σ_coh used in the cosmological fits.

Sample	σ_coh

low-z	0.134
SDSS-II	0.108
SNLS	0.080
HST	0.100

Notes. Those values correspond to the weighted mean per survey of the values shown in Fig. 7, except for HST sample for which we use the average value of all samples. They do not depend on a specific choice of cosmological model (see the discussion in Sect. 5.5).
