I updated the TCS IFO model/simulation page. The major changes and additions are summarized below:

OPTIC LENS/ROC model (left side of screen):

• Changed the model file so everything in the simulation is under one SIM block that is added to the main H1TCSCS model. This had the effect of reversing names that were being used last week (H1:TCS-ITMX_SIM goes to H1:TCS-SIM_ITMX, etc)
• Moved the channel for QPD transmission calibration (into Watts in the arm) into only one channel per arm, previously there were two, and called them H1:TCS-SIM_X(Y)ARM_POWER_WATTS_PER_INPUT_UNIT
• Added a channel sums the the Kalman aposteriori correction to the defocus/ROC based on measurements from the HWS. This is for future implementation of a Kalman state estimator of the thermal state

IFO SIMULATOR:

This is a set of calculations of interferometer values that are dependent on ROC and ITM lenses

• Common and Differential thermal lenses in the Short Michelson
  • H1:TCS-SIM_IFO_COMMON_LENS_MICH_OUTPUT
    H1:TCS-SIM_IFO_COMMON_LENS_MICH_OUTPUT
  • H1:TCS-SIM_IFO_DIFF_LENS_MICH_OUTPUT
• Common ITM ROC
  • H1:TCS-SIM_IFO_COMMON_ITM_ROC
• ABCD matrices and Round-trip Gouy Phases of the SRC and PRC
  • H1:TCS-SIM_IFO_PRC_RT_A
  • H1:TCS-SIM_IFO_PRC_RT_B
  • H1:TCS-SIM_IFO_PRC_RT_C
  • H1:TCS-SIM_IFO_PRC_RT_D
  • H1:TCS-SIM_IFO_PRC_RT_GOUY_PHASE
  •  
• Arm cavity G-factors
  • H1:TCS-SIM_IFO_G_XARM_OUTPUT
• Arm cavity higher order transverse mode spacing (in Hz)
  • H1:TCS-SIM_IFO_XARM_HOM_SPACING_HZ_OUTPUT
• (Provisional): torsional radiation pressure spring constant

The MEDM screen is being (slowly) updated to illustrate these parts
