specsrbench.figures.fig5_per_line_snr¶
Figure 5 – per-line behaviour: S/N, detection, false detection, width bias.
Four rows over the four diagnostic lines. The first two say how much signal a method reports and how often it reports any; the last two are what stop those being read as quality.
Median S/N, over the subset where the reference itself detects the line.
Detection fraction at S/N > 5, with the reference’s own rate marked.
False detection rate – how often a method reports S/N > 5 where the reference says the line is absent (S/N < 3). This is the row where SR2 separates from every classical method: 0.30 on Hbeta and 0.44 on [O II], against <= 0.09 for anything classical.
FWHM bias in nanometres against the reference’s fitted width.
A method can lead the first row by inventing lines, and only the third row shows it. They are drawn together for that reason.
Module Attributes
The reference detects a line above this; below TRUE_ABSENT it says there is none, and anything a method "finds" there is false. |
|
Widths are only meaningful where the reference line is solidly detected. |
