SearchFFT: off-axis Fringe Tracking and Adaptative Optics for interferometry

This tool searches for nearby stars suitable for off-axis Fringe Tracking and off-axis Adaptive Optics.
You can query one or several Science Targets separated by semicolon by names (resolved using Simbad for proper motion) or by coordinates (RA +/-DEC J2000). For each of them, suitable solutions will be searched. Only solutions with a valid AO and a valid FT are presented. When several solutions are found, a scoring ( \(strehl_{SCI} . exp( -\sigma_{\phi}^2 ) . exp( -\sigma_{iso}^2 )\) ) and ranking is proposed based on a simplified model of AO (GPAO) and FT (GRAVITY) of VLTI. If the Science Target allows it, the on-axis solution is also presented and ranked.

For the time being, only the NGS mode of GPAO is supported by the scoring. However, solutions can be found for the LGS mode by increasing the AO magnitude (but with wrong scoring and ranking).
SIMBAD and Gaia DR3 catalogues are cross-matched though CDS and ESA data centers. Each query is performed within a search radius around the Science Target below a max declinaison. A magnitude filter is applied to define candidates for the FT (infrared) and for the AO (visible). Only solutions with a valid AO and a valid FT are presented in the main output table. For debug or further investigations, the list of all individual candidates can be found in the extended raw result.
