Summary Report

Type-A

  • GAS drift was large in EY from 10/25.

Type-B

  • SR3: With new geophone inter-calibration factors, Lucia implemented the inertial damping and updated Guardian.
  • SR2:
    • Lucia implemented inertial damping and upated Guardian.
    • Fabián wrote a Jupyter notebook based on Terrence's tutorial for blending geophone and LVDT using the methods he developed. It's still a work on progress.

Type-Bp

  • PRM: Ushiba-san did diagonalization of the BF and oplev.
