Caveats
No source-specific caveats are recorded.
Type Ia light-curve standardization relies on the Phillips relation (stretch factor s, or dm15): brighter SNe Ia decline slower, with ~0.14 mag difference per 0.5 unit of decline rate, enabling reduction of intrinsic scatter from ~0.5 mag to ~0.15 mag.
