[RMS_below300m 欄位說明]
  來源  : 2024 backfill nc（100Hz decimated，Hole A trace 1307–1403，跳過頂部 73 ch，對應深度 ~300–700 m）
  前處理: per-file bad-channel masking(median+10×MAD) → bandpass 1–20 Hz（sosfiltfilt，逐檔獨立，非跨檔 causal filter state）
  公式  : sqrt( sum(x[ch,t]^2) / (97 ch × 100 samples) ) / DAS_SENSITIVITY
  意義  : STA/LTA 偵測峰值那一秒，97 個 channel × 100 個取樣點的 RMS 振幅
  單位  : strain rate (1/s)，已轉換為物理應變率（DAS_SENSITIVITY=7.0621e+08）
  參考值: 典型背景 ~7.08e-10–2.83e-09，大地震 > 1.13e-08
