  • Duotone 36Hz and 960Hz are inconsistnt.
  • Duotone and Pcal-XY timedelay are inconsistent.
  • Pcal-XY time delay and Swept sine injection are consistent within 1 sigma error.
  • herr/C00 and hctrl/C00 is also consistent.
  • Mod_Fil include S-Z.
  • Mod_Fil include resG29().
  • 5 days parameter estimation wiht swept sine.
