Table 3
Each line shows Hubble residual fit quality for a given standardization method, measured relative to a reference fit based on post-peak uTi data without any host property corrections (first line).
| Standardizing | Host step | Nbr SNe |  |
P(AICc) |
|---|---|---|---|---|
| property | Ratio | |||
| uTi@p6 | None | 57 | 0 | 1.0 |
| Global mass | 47 | − 1.9 | 0.19 | |
| LsSFR | 47 | − 4.8 | 0.84 | |
| x1 | None | 57 | 20.5 | 3.6e − 5 |
| Global mass | 47 | 5.6 | 0.0045 | |
| LsSFR | 47 | 1.9 | 0.029 | |
| uTi@p6 + uCa@m6 | None | 43 | − 17.2 | 1521.5 |
| Global mass | 35 | − 12.0 | 5.0 | |
| LsSFR | 35 | − 15.9 | 33.7 | |
Notes. Each comparison is made using only the SNe in common (Nbr SNe) for a given measurement. The penultimate column shows the difference in χ2 assuming Hubble residuals are described using one or two Gaussian distributions (the latter when a host property step is included). The final column gives the likelihood according to the sample-size corrected Akaike Information Criteria (AICc), again relative to the first line uTi model.
