• Call: import fullseye as fs; fs.ledger.chirp_mass_from_track(track) -> 'dict' (to call the implementation directly, import gwsearch; gwsearch.chirp_mass_from_track(track) -> 'dict'; from the registry, ops1d.get("chirp_mass_from_track"))
Chirp mass and coalescence time from a gravitational-wave frequency track (t, f) by least squares.
> The detailed description below is the original text — the summary and the headings are translated.
track : array_like
(N, 2) の pairs: 列 0 = 時刻 [s]、列 1 = 重力波周波数 [Hz] (正)。N ≥ 3。
dict
chirp_mass_msun、coalescence_time_s(t_c = a/b)、slope(b)、
residual_rms(f^{−8/3} の当てはめ残差)、n_points、rising(周波数が
時間とともに上がる軌跡か)。上がらない軌跡はインスパイラルではないので
rising = False とし、chirp_mass_msun と coalescence_time_s は None
(例外にはしない —— 「鳴いていない」は正しい答え)。
f^{−8/3} = a − b·t、b = (8/3)(96/5)π^{8/3}(GM_c/c³)^{5/3}。PRL 116, 061102 の式 (1) の積分形。
