Accurate photometry with adaptive optics in the presence of anisoplanatic effects with a sparsely sampled PSF [PDF]
, 2009 Anisoplanatic effects can cause significant systematic photometric uncertainty in the analysis of dense stellar fields observed with adaptive optics. Program packages have been developed for a spatially variable PSF, but they require that a sufficient ...

Photometry with adaptive optics: A first guide to expected performance [PDF]
, 1998 This paper aims to help prospective observers estimate the likely performance of adaptive optics for pho- tometric observations. Both real and simulated adaptive optics data are used in specic examples covering the ma- jor observational situations. These

Adaptive Optics Photometry and Astrometry of Binary Stars. II. A Multiplicity Survey of B Stars [PDF]
, 2007 We carried out a search for companions to B stars using the adaptive optics system of the Advanced Electro-Optical System 3.6 m telescope. We observed 70 B stars in the I band, finding 16 companions, 10 of which are newly discovered companions.

Estimation of Differential Photometry in Adaptive Optics Observations with a Wavelet-based Maximum Likelihood Estimator [PDF]
, 2011 We propose to use the Bayesian framework and the wavelet transform (WT) to estimate differential photometry in binary systems imaged with adaptive optics (AO).

Optical and Infrared Photometry of SN 2005df [PDF]
arXiv, 2017 We present optical BVRI and near-infrared YJHK_s photometry of the normal Type Ia supernova 2005df, obtained with the CTIO 1.3-m and 0.9-m telescopes. The B- and V-band photometry, S-corrected to the filter prescriptions of Bessell(1990), matches the corresponding photometry from the ANU published by Milne et al. (2010). The R-band photometry from CTIO

HIGH-CADENCE, HIGH-CONTRAST IMAGING FOR EXOPLANET MAPPING: OBSERVATIONS OF THE HR 8799 PLANETS WITH VLT/SPHERE SATELLITE-SPOT-CORRECTED RELATIVE PHOTOMETRY [PDF]
Astrophysical Journal, 2016 Time-resolved photometry is an important new probe of the physics of condensate clouds in extrasolar planets and brown dwarfs. Extreme adaptive optics systems can directly image planets, but precise brightness measurements are challenging. We present VLT/
