The Tierras Observatory: An ultra-precise photometer to characterize nearby terrestrial exoplanets
Juliana García-Mejía, David Charbonneau, Daniel Fabricant +4
We report on the status of the Tierras Observatory, a refurbished 1.3-m ultra-precise fully-automated photometer located at the F. L. Whipple Observatory atop Mt. Hopkins, Arizona.…
A collimated beam projector for precise telescope calibration
Michael Coughlin, T. M. C. Abbott, Kairn Brannon +7
The precise determination of the instrumental response function versus wavelength is a central ingredient in contemporary photometric calibration strategies. This typically entails…
A Digital Correlator Upgrade for the Arcminute MicroKelvin Imager
Jack Hickish, Nima Razavi-Ghods, Yvette C. Perrott +18
The Arcminute Microkelvin Imager (AMI) telescopes located at the Mullard Radio Astronomy Observatory near Cambridge have been significantly enhanced by the implementation of a new…
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…
A framework for modeling the detailed optical response of thick, multiple segment, large format sensors for precision astronomy applications
Andrew Rasmussen, Pierre Antilogus, Pierre Astier +11
Near-future astronomical survey experiments, such as LSST, possess system requirements of unprecedented fidelity that span photometry, astrometry and shape transfer. Some of these…
The Pan-STARRS1 Photometric System
J. L. Tonry, C. W. Stubbs, K. R. Lykke +11
The Pan-STARRS1 survey is collecting multi-epoch, multi-color observations of the sky north of declination -30 deg to unprecedented depths. These data are being photometrically and…
Precise Throughput Determination of the PanSTARRS Telescope and the Gigapixel Imager using a Calibrated Silicon Photodiode and a Tunable Laser: Initial Results
Christopher W. Stubbs, Peter Doherty, Claire Cramer +5
We have used a precision calibrated photodiode as the fundamental metrology reference in order to determine the relative throughput of the PanSTARRS telescope and the Gigapixel ima…
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…
