PSF Software Notes

From Kellee's notes during TCS training, Summer-2017

Functionality

JHill diagram - LUT=lookup table, GATE= can be turned on/off; USR=user
Active Optics Command and Data Flow

What is IIF commands to PSF - instrument commands (LBC setWavefront, setFocus for example)

out/inner glass thermocouples - difference calculated in PSF

Primary-to-secondary offloads planned, but not implemented

Reinit of PSF will re-read configuration

IIF allows selection of optic or not (not means let PSF decide)

Zrot == selection angle on tertiary
3 actuators on tertiary

Can change focus, tip tilt, and coma with mirror, but not done in practice

everything you can do with position changes, needs to be done that way so you don't take up the "force budget"

Errors

PSF "revert" is "clear active optics" -- sends commands to AO and can get exceptions or failures

PSF monitors actual vs requested positions and complains if the errors get too big
