Local monitoring of atmospheric transparency from the NASA MERRA-2 global assimilation system
A. Guyonnet, S. Dagoret-Campagne, N. Mondrik
Ground-based astronomy has to correct astronomical observations from the impact of the atmospheric transparency and its variability.The current objective of several observatories i…
An Overview of the LSST Image Processing Pipelines
James Bosch, Yusra AlSayyad, Robert Armstrong +31
The Large Synoptic Survey Telescope (LSST) is an ambitious astronomical survey with a similarly ambitious Data Management component. Data Management for LSST includes processing on…
Testing of the LSST's photometric calibration strategy at the CTIO 0.9 meter telescope
Michael W. Coughlin, Susana Deustua, Augustin Guyonnet +4
The calibration hardware system of the Large Synoptic Survey Telescope (LSST) is designed to measure two quantities: a telescope's instrumental response and atmospheric transmissio…
High fidelity point-spread function retrieval in the presence of electrostatic, hysteretic pixel response
Andrew Rasmussen, Augustin Guyonnet, Craig Lage +11
We employ electrostatic conversion drift calculations to match CCD pixel signal covariances observed in flat field exposures acquired using candidate sensor devices for the LSST Ca…
The DICE calibration project: design, characterization, and first results
N. Regnault, A. Guyonnet, K. Schahmanèche +12
We describe the design, operation, and first results of a photometric calibration project, called DICE (Direct Illumination Calibration Experiment), aiming at achieving precise ins…
Evidence for self-interaction of charge distribution in charge-coupled devices
A. Guyonnet, P. Astier, P. Antilogus +2
Charge-coupled devices (CCDs) are widely used in astronomy to carry out a variety of measurements, such as for flux or shape of astrophysical objects. The data reduction procedures…
The brighter-fatter effect and pixel correlations in CCD sensors
P. Antilogus, P. Astier, P. Doherty +2
We present evidence that spots imaged using astronomical CCDs do not exactly scale with flux: bright spots tend to be broader than faint ones, using the same illumination pattern.…
(Sn)DICE: A Calibration System Designed for Wide Field Imagers
N. Regnault, E. Barrelet, A. Guyonnet +5
Dark Energy studies with type Ia supernovae set very tight constraints on the photometric calibration of the imagers used to detect the supernovae and follow up their flux variatio…
LSST: from Science Drivers to Reference Design and Anticipated Data Products
Željko Ivezić, Steven M. Kahn, J. Anthony Tyson +310
(Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a sin…
