Mitigating the Non-Linearities in a Pyramid Wavefront Sensor
Finn Archinuk, Rehan Hafeez, Sébastien Fabbro +2
For natural guide start adaptive optics (AO) systems, pyramid wavefront sensors (PWFSs) can provide significant increase in sensitivity over the traditional Shack-Hartmann, but at…
Optimal stellar photometry for multi-conjugate adaptive optics systems using science-based metrics
P. Turri, A. W. McConnachie, P. B. Stetson +5
We present a detailed discussion of how to obtain precise stellar photometry in crowded fields using images from multi-conjugate adaptive optics (MCAO) systems, with the intent of…
Astrometry with MCAO: HST-GeMS proper motions in the globular cluster NGC 6681
D. Massari, G. Fiorentino, A. McConnachie +7
Aims: for the first time the astrometric capabilities of the Multi-Conjugate Adaptive Optics (MCAO) facility GeMS with the GSAOI camera on Gemini-South are tested to quantify the a…
Towards Precision Photometry with Extremely Large Telescopes: the Double Subgiant Branch of NGC 1851
P. Turri, A. W. McConnachie, P. B. Stetson +4
The Extremely Large Telescopes currently under construction have a collecting area that is an order of magnitude larger than the present largest optical telescopes. For seeing-limi…
Using Site Testing Data for Adaptive Optics Simulations
Glen Herriot, David Andersen, Rod Conan +8
Astronomical Site testing data plays a vital role in the simulation, design, evaluation and operation of adaptive optics systems for large telescope. We present the example of TMT…
