Rationale
The NEAT (Nearby Earth Astrometric
Telescope) mission is a proposition for a M-size
mission within the Cosmic Vision 2015-2025 plan. The
main scientific goal of the NEAT mission is to detect
and characterize planetary systems in an exhaustive
way down to 1 Earth mass in the habitable zone and
further away, around nearby stars for F, G, and K
spectral types. This survey would provide the actual
planetary masses, the full characterization of the
orbits including their inclination, for all the
components of the planetary system down to that mass
limit. The main science drivers are identification of
Terrestrial planets in the habitable zone of nearby
solar-type stars, constraints for planetary formation
scenario, interaction of planets in planetary systems,
exploration of a new part of the parameter space to
understand the diversity of exoplanets.
As discussed during the NEAT workshop in Nov 2011, it is time to start "data simulator" activities for NEAT. The idea is to merge different software tools to build a pipeline that will be able to transform any given planetary systems in realistic NEAT signals including different sources of noises. Once the pipeline will be ready, we will generate random planetary systems, transform them to astrometric signals and see if the NEAT data processing teams are able to retrieve the characteristics of the systems with adequate accuracy.
The idea is to gather the competences of different groups:
The result of this work will provide the mandatory design requirements and demonstrate the capabilities of high precision astrometry mission coupled with RV and Gaia to find all planetary components down to the Earth mass around our close neighbours.

The idea is to gather the competences of different groups:
1- planetary population synthesisThe 2013 NEAT workshop is aimed at gathering experts from the different fields to build the NEAT simulator and run a double blind test with hidden initial values to be retrieved.
2- planetary dynamics to generate ephemeris
3- generation of stellar noises
4- attribute each system to an actual star with reference stars
5- Define a baseline astrometric and Doppler model
6- Generate photometry, radial velocities and differential astrometry
7- Simulate realistic Doppler measurements and cadence
8- Simulate Gaia observations (~50uas/epoch x 80 epochs)
9- Simulate 50 measures of 0.8uas/sqrt(h) NEAT signals and add realistic instrumental noise
10-Data processing code to retrieve the parameters of the planetary systems
The result of this work will provide the mandatory design requirements and demonstrate the capabilities of high precision astrometry mission coupled with RV and Gaia to find all planetary components down to the Earth mass around our close neighbours.
