Astrometry and photometry in high contrast imaging: ADI/LOCI biases and the SOSIE/LOCI solution

Raphael Galicher & Christian Marois
The direct exoplanet imaging field will strongly benefit from the higher angular resolution achieved by next generation 30+m telescopes. To fully take advantage of these new facilities, one of the biggest challenges that ground-based adaptive optics imaging must overcome is to derive accurate astrometry and photometry of point sources. The planet photometry and its astrometry are used to compare with atmospheric models and to fit orbits. If erroneous numbers are found, or if errors are...
