Purpose:
- To prepare a noise model of the MC and prepare an error budget for MC length fluctuations
Step 1. Collection of existing tools and models prepared by others.
- List of previous related work and examples of noise models
Step 2. Prepare a toy model of a generic feedback loop with two noise sources as a pedagogic exercise (Wed 15th Feb)
Step 3. Make a model for the MC -> PSL feedback loop with various sources of noise (Wed 22nd Feb)
Step 4. Measure the MC loop noise (Wed 29th Feb)
Step 5. Obtain the error budget plot. (Wed 8th March)
Step 6. Include ASC noise from the WFS loops in the model (Wed 15th March)
Step 7 Measure ASC noise in the instrument
Step 8 Improve the ASC servo filter shape to reduce the ASC noise injected into the MC loop.
