Summary Report

Type-A

  • Implemented the modified blending filters to the IP controls.

Type-B

  • Fabián wrote a script for the inter-calibration of the seismometer on the ground and the F0 LVDT.
  • Lucia measured some TFs (from the seismometer to F0 LVDT) that can be used to calculate such a factor using the script.

Type-Bp

Type-C

  • Monitored the OMMT1/2/OSTM suspensions during the pump down. All of OSEMs stay in the linear range.

Electronics

Control

  • Some blocks were added to the MEDM screen for Type-B.

Schedule
