Summary of the variants of the BLS routine.
| Name | Fixed parameters | Description |
|---|---|---|
| BLS0 | None | BLS spectrum S/N maximization, |
| uniform weights: | ||
| T0 [α], H# [1 − α] | ||
| BLS1 | Tc, t14 | Zero point and δ fit, |
| optimized weights as for BLS0 | ||
| BLS2 | Tc, t14, δ | Zero point fit, |
| optimized weights as for BLS0 | ||
| BLS3 | BLS0+BLS1 | BLS spectra are inverse variance |
| weighted (see Eq. (3)); | ||
| data weights (α, see text) are kept | ||
| fixed for BLS1 but varied for | ||
| BLS0 to yield the maximum | ||
| S/N for the BLS3 spectrum |
