CAL meeting 20200608

  • Yuki & S.Takahiro Final decision of C20 h(t)

    • 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.
    • Action items
      • Filter list in document -> Yuki and Sawada
