…d and optional S-wave criterion Replace the single best peak and the MAD-ratio trigger (removed) with a sliding correlate_template + find_peaks at template_cc_min, so several events can be detected per chunk; add t_min spacing, sub-sample interpolation, decim_factor, zero-phase filtering, and an optional S-wave NCCs combined criterion with a ccs column.

Salut Claudio,
Le cœur du stage.
scan_templatespasse d'un pic unique par chunk (déclenché par le ratio cc/MAD) à une corrélation glissantecorrelate_template+find_peaksau seuiltemplate_cc_min: plusieurs événements détectables par chunk. La MAD (min_cc_mad_ratio) est retirée, comme tu le souhaitais.Inclus aussi : fusion des pics trop proches (
t_min), interpolation sous-échantillon du pic, décimationdecim_factoravec anti-repliement pour la vitesse, passe-bande zéro-phase. En option (off par défaut) : une seconde corrélation centrée sur les ondes S (NCCs) et un critère combiné entièrement paramétrable, avec une colonneccsajoutée àtemplate_detections(migration en place).Point de nommage à trancher : j'ai introduit
template_cc_mincarcc_minexiste déjà (0.95, similarité des paires du clustering). Dis-moi si tu préfères réutilisercc_min.Tests unitaires (dont un test d'injection synthétique) et une note de réglage des performances ajoutés.
