Best-fit values for the parameters of Eq. (1).
| Sample | cint | σc | τ |
|---|---|---|---|
| Full sample | −0.085 ± 0.004 | 0.030 ± 0.005 | 0.155 ± 0.007 |
| Dustless sample | −0.087 ± 0.008 | 0.033 ± 0.008 | 0.102 ± 0.010 |
| Non dustless sample | −0.082 ± 0.005 | 0.029 ± 0.006 | 0.166 ± 0.008 |
Notes. The full sample, the dustless, and the not-dustless samples are defined in Sect. 3. The dustless sample comprises SNe Ia that are located in the outskirts of their host galaxies and in locally low-mass environments.
