Presentations:
tbdLSST Overview: Actuators, Perturbations, Controls, and Metrics
Action items:
- Aberration modeling
- Check the accuracy of the assumption of linearity in the sensitivity matrix
- Bo will give Aaron and Michael the sensitivity matrices he has derive
- Michael will interpolate to a new position see if his predicted values are “better” (better means doesnt impact the PSSN by more than 10-3)
- Compare the Galsim wavefront sensor simulations
- Michael will compare the wavefront images using the LSST Zemax model (from Aaron)
- Once this comparison is complete Bo will provide Michael zemax images and the zernicke coefficients and Michael will compare
- Check the accuracy of the assumption of linearity in the sensitivity matrix
- Optical model
- Provide GalSim with spider description (either from phosim or the latest model) and post on confluence page
- Atmospheric modeling
- Josh validate his model comparing against Arroyo, looking at structure function, dependence on screen size
- Provide Josh with the distributions for the wind velocities and directions, CN2 (either from phosim or somewhere else)
- Possible to use Josh's work to validate effects of assuming photon based approach for the atmosphere (after it is validated) but recognizing that phosim has done many of these tests
