Initial Assessment of Monocrystalline Silicon Solar Cells as Large-Area Sensors for Precise Flux Calibration
Sasha Brownsberger, Nicholas Mondrik, Christopher W. Stubbs
As the precision frontier of large-area survey astrophysics advances towards the one millimagnitude level, flux calibration of astronomical instrumentation remains an ongoing chall…
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 increased rate of large flares at intermediate rotation periods for mid-to-late M dwarfs
Nicholas Mondrik, Elisabeth Newton, David Charbonneau. Jonathan Irwin
We present an analysis of flares in mid-to-late M dwarfs in the MEarth photometric survey. We search 3985155 observations across 2226 stars, and detect 54 large () f…
New rotation period measurements for M dwarfs in the southern hemisphere: an abundance of slowly rotating, fully convective stars
Elisabeth R. Newton, Nicholas Mondrik, Jonathan Irwin +2
Stellar rotation periods are valuable both for constraining models of angular momentum loss and for under- standing how magnetic features impact inferences of exoplanet parameters.…
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…
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…
