Description

Invites the LIGO Cal team to

provide the actual Pcal line displacement amplitudes [m] and per-stage actuator line drives [counts/N/m] + exact O3/O4 frequencies,
so we can replace the single representative A_tot in darm_callines.O3_LINES/O4_LINES with real per-line heights and report absolute (not just ratio) times.

Points at example 08 and cites Sun 2020 / Cahillane 2017 / arXiv:2508.08423.
