Performance of Kitt Peak's Mayall 4-meter Telescope During DESI Commissioning
Aaron M. Meisner, Behzad Abareshi, Arjun Dey +21
In preparation for the Dark Energy Spectroscopic Instrument (DESI), a new top end was installed on the Mayall 4-meter telescope at Kitt Peak National Observatory. The refurbished t…
Petabytes to Science
Amanda E. Bauer, Eric C. Bellm, Adam S. Bolton +24
A Kavli foundation sponsored workshop on the theme \emph{Petabytes to Science} was held 12 to 14 of February 2019 in Las Vegas. The aim of the this workshop was to di…
Overview of the DESI Legacy Imaging Surveys
Arjun Dey, David J. Schlegel, Dustin Lang +157
The DESI Legacy Imaging Surveys are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Surve…
Maximizing Science in the Era of LSST: A Community-Based Study of Needed US Capabilities
Joan Najita, Beth Willman, Douglas P. Finkbeiner +48
The Large Synoptic Survey Telescope (LSST) will be a discovery machine for the astronomy and physics communities, revealing astrophysical phenomena from the Solar System to the out…
Crowdsourcing quality control for Dark Energy Survey images
P. Melchior, E. Sheldon, A. Drlica-Wagner +47
We have developed a crowdsourcing web application for image quality control employed by the Dark Energy Survey. Dubbed the "DES exposure checker", it renders science-grade images d…
Monitoring the atmospheric throughput at Cerro Tololo Inter-American Observatory with aTmCam
Ting Li, D. L. DePoy, J. L. Marshall +3
We have built an Atmospheric Transmission Monitoring Camera (aTmCam), which consists of four telescopes and detectors each with a narrow-band filter that monitors the brightness of…
aTmcam: A Simple Atmospheric Transmission Monitoring Camera For Sub 1% Photometric Precision
Ting Li, D. L. DePoy, R. Kessler +8
Traditional color and airmass corrections can typically achieve ~0.02 mag precision in photometric observing conditions. A major limiting factor is the variability in atmospheric t…
