Cuts applied to produce our final sample.
| Criterion | No. of SNe | Removed |
|---|---|---|
| DR2 | 3628 | – |
| z ≤ 0.06 | 1584 | 2044 |
| Light curve coverage conditions (a) | 976 | 608 |
| GP length scale < 44 d | 973 | 3 |
| σt2(r) < 5.9 d | 928 | 45 |
| σℱr2 < 0.05 | 898 | 30 |
| Manual inspection of outliers | 893 | 5 |
| Cosmological sub-sample (b) | 783 | 110 |
Notes.
Light curve coverage conditions require detections in at least two filters, in at least one filter pre-max and at least one filter post-max. At least two detections pre-peak and at least two detections post peak. A minimum of seven detections across all filters, and a minimum of four detections between +10 and +40 d in the r band.
Sub-sample of SNe Ia that pass the following cuts: classified as normal or 91T-like, |x1|< 3, |σx1|≤1, −0.2 ≤ c ≤ 0.8, |σc|≤0.1, |σt0|≤1, and fit-probability > 1e−7 (see Sect. 3.6).
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.
