Constraining the Adaptive Optics Point-Spread Function in Crowded Fields: Measuring Photometric Aperture Corrections
The point-spread function (PSF) of an adaptive optics (AO) system is often poorly known. This ignorance can lead to significant systematic errors. Since the degree of AO correction is sensitive to the observing conditions: seeing, wind speed, brightness of the wavefront reference, etc., it would be desirable to estimate the PSF from the data themselves rather than from observations of a PSF sta...
متن کاملPhotometric Aperture Corrections for the ACS/SBC
We present aperture correction tables for the Advanced Camera for Surveys Solar Blind Channel (ACS/SBC). As part of a campaign to improve the instrument calibrations, we observed the white dwarf J132811.4+463050 using three filters (F125LP, F140LP, F150LP). The observed point spread functions (PSFs) contain more flux in the wings than Tiny Tim models, which can underestimate aperture correction...
متن کاملExtraction of the Photometric Information : Corrections
We present here the set of corrections that will be applied to the raw data of the CoRoT mission. The aim is to correct the data for instrumental and environmental perturbations as well as to optimize the duty-cycle, in order to reach the expected performances of the mission. The main corrections are : the correction of the electromagnetic interferences, suppression of outliers, the background ...
متن کاملPhotometric biases due to stellar blending: implications for measuring distances, constraining binarity and detecting exoplanetary transits
We investigate blending, binarity and photometric biases in crowded-field CCD imaging. For this, we consider random blend losses, which correspond to the total number of stars left undetected in unresolved blends. We present a simple formula to estimate blend losses, which can be converted to apparent magnitude biases using the luminosity function of the analyzed sample. Because of the used ass...
متن کاملThe Anisoplanatic Point-Spread Function in Adaptive Optics
The effects of anisoplanatism on the adaptive optics point-spread function are investigated. A model is derived that combines observations of the guide star with an analytic formulation of anisoplanatism in order to generate predictions for the adaptive optics point-spread function at arbitrary locations within the field of view. The analytic formulation captures the dependencies of anisoplanat...
