Minutes
Attendees: David L., Thomas B., Torri J., Patrick M., Jiawei G., Naomi J., Malachi S., Armen K.
- (Slides from last week need to be uploaded to minutes)
- First 10 days of Spring 2020 data identified nudge events comparison started
- Some initial confusion on what period of time statistics produced from Patrick's and Jiawei's algorithms covered. This was sorted out and determined that they were roughly the same order of magnitude but will need to look offline to get exact numbers.
- Some discussion on the maximum lag between pushing a nudge button and seeing the result. This is assumed to be 10 seconds.
- This is significant on how multiple nudges are combined into a single nudge event. (May be different in the two algorithms)
- Naomi brought up what happens if beam goes down between pushing button and response. Patrick responded that the nudge events only end after the beam has been up for at least 30 seconds after the button was pressed.
- There was some more discussion on the "c" angle as defined in Livingston's paper.
- Some clarification on how AI can be used here. Specifically, AI can use recent measurements of the coherent edge and possibly other environmental factors to predict the position of the edge at a point shortly in the future. This can them be used to calculate delta-c which the standard tools can translate into changes to the goniometer angle.
- Patrick asked for the values/transformations that are used to convert a change in c into changes int the yaw and pitch angles.
Action Items
- Update last meeting's minutes with slides from Patrick and Jiawei (David)
- Add columns to appropriate dataframe for the edge position from start of run and from the nominal (Jiawei)
