Table A.2

Probability of detecting models for SN Ia evolution.

Indicator 0 10 20 30 40 Low-met Hi-met

pEW f3 0 1 2 3 5 3 2
pEW f4 0 1 2 3 4 0 1

pEW f3+f4 0 1 3 4 5 2 2

Notes. Each column corresponds to one model (first column is no evolution), see text for further description. Each row corresponds to a search for evolution using the specified spectral indicator, assuming the population changes linearly with redshift. Numbers are the detection level in standard deviations when removing highest bias events. The last line is an example where measurements of two indicators are combined to increase sensitivity.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
