== Status

* DFS meeting 9-10 september at Groningen


= Action items

Read GeMS first on-sky results (Rigaut+ SPIE 2012) in more detail:
-appears very relevant benchmark (MCAO, 8.1meter telescope, LGS) for MICADO + MAORY 39m E-ELT. Only reality-case I now know off.
-astrometric pipeline in paper simplistic. Yet no indication of hitting intra-night dynamic systematics for relative astrometry downto at least ~400microarcsec.
Not covered in paper:
-inter-night/epoch dynamic systematics
-static systematics: is MICADO calibration mask sufficient to monitor this? On-sky near polar field also needed? 
I have emailed Rodrigo Carrasco ( a GeMS instrument scientist) to get to their experience on these. No response yet.
-to do: determine if MAD is another benchmark.

== Action items

* MICADO simulated images. Provided by Remko et al.:
   * step0: ideal detectors (no detector rotations, pixelscale differences). Ideal MICADO: no geometric distorsion from MICADO optics.
   * step1: include distorsions due to ADC (series of ADC designs?)
   * step2: add distorsions due to atmosphere 
* Astrometric testbed pipeline to process MICADO simulated images. Provided by Gijs et al.
  * Current status: rms=1/10th pixel / 1/20th PSF (exposure-to-exposure) accuracy for real optical/near-IR data from telescope not optimized for astrometry. 
    * accuracy of external catalog folded in.
  * source extraction (Sextractor extraction sufficient?)
  * astrometric solution based on single exposure (use current astrometric pipeline (LDAC). Reference catalog = true positions?)
  * astrom solution based on ensemble of (dithered) exposures (use current astrometric pipeline (SCAMP and/or LDAC))
  * output: x,y,ra,dec of stars + parametric fit to systematic distorsions over FoV.
* Austria - NL MICADO meeting 9-10 sep (conflict Gijs)
   * astrom postdoc plan: high-precision astrometry (from local to global)
      * science cases: MICADO (Eline+Koen) + workout AGN
      * instruments: local astrom: MAD, GEMS, HST, MICADO-SIM, 
      * global astrom: Euclid-KiDS
      * LDAC
   * Project postdoc/PhD plan on time-line: NL status: funding, HR
   *
