Outcomes of Workshop Week 2018!

There will be no conference or workshop proceedings.

Presentations and poster PDFs will be available here, after the workshop (where provided).

Over 100 participants took part in Workshop Week 2018!

Notes were taken during the discussion periods, and relevant parts are provided here.

Reconstruction and control

Link to google doc for desired features in simulations

Unsolved problems:

  • Island effect
  • Non-stationarity and boiling (stats change, v, r0, L0 (f(t)), cn2 profiles evolving, geometry (telescope rotation etc)
  • Low wind effect
  • Uplink for LGS
  • Elongation and truncation
  • Chromaticity, atmospheric dispersion
  • Scintillation
  • Quasi statics
  • Vibration and flexures, wind buffeting.
  • Sodium density profile (including clustering)
  • Non-common path aberrations
  • Fratricide
  • Robustness to sodium layer micrometeorites

Simulation

Required aspects for forthcoming simulations:

  • Developer and user manuals (aimed at PhD students)
  • Non-stationary simulations
  • Boiling (srinath 2015 paper, includes parameter estimation
  • Longer simulations
    • variations within a simulation
    • robustness
  • Widefield - tilted DMs and conjugation
  • Dispersion
  • Chromatic pyramids
  • GUIs
  • Wide-field camera effects
  • Effect of instrument behind AO
    • integrated modelling
  • Wide-field NCPA

PSF reconstruction

Common suggested approach (TMT, LAM) is to try to get information about what PSF parameters are required for the different science cases.

Fields with no PSF sources (all extended) can be problematic.

Observabes

Relative measurements: Separations, red/blueshifts, shape/morphology/contrasts

Absolute: Astromoetrym photometry, contrast

psf-R tools for astronomers - how to use the PSF:

Needs to be reliable - how to quantify

General purpose tools - eg SExtractor, needs to be integrated with these

Team up with astronomers

Depends on science case

Static aberrations - requires a lot of effort.

Understand how the astronomers use the PSF

Understand the limitations

Instrumental pipelines - good when in github and Python.

Should be astronmy driven (but we know what they should want)

Needs proof that it works

How to handle the data

- psf with the image?

- full telemetry data?

For HARMONI, PSF-R is not a deliverable, but will provide a crude real-time PSF, and data on a non-persistent server.

Presentations

We have a 150MB file size limit, so some presentations have been converted to PDF to reduce size where necessary.
