Uncovering Hidden Systematics in Extreme-Precision Radial Velocity Measurements
Lily L. Zhao, Debra A. Fischer, Andrew E. Szymkowiak +2
We identify and correct for small but coherent instrumental drifts in seven years of radial velocity data from the EXtreme PREcision Spectrograph (EXPRES). The systematics are most…
Performance Verification of the EXtreme PREcision Spectrograph
Ryan T. Blackman, Debra A. Fischer, Colby A. Jurgenson +25
The EXtreme PREcision Spectrograph (EXPRES) is a new Doppler spectrograph designed to reach a radial velocity measurement precision sufficient to detect Earth-like exoplanets orbit…
An Extreme Precision Radial Velocity Pipeline: First Radial Velocities from EXPRES
Ryan R. Petersburg, J. M. Joel Ong, Lily L. Zhao +13
The EXtreme PREcision Spectrograph (EXPRES) is an environmentally stabilized, fiber-fed, , optical spectrograph. It was recently commissioned at the 4.3-m Lowell Discove…
Modeling the Echelle Spectra Continuum with Alpha Shapes and Local Regression Fitting
Xin Xu, Jessi Cisewski-Kehe, Allen B. Davis +2
Continuum normalization of echelle spectra is an important data analysis step that is difficult to automate. Polynomial fitting requires a reasonably high order model to follow the…
CHIRON TOOLS: Integrated Target Submission, Scheduling and Observing Systems for a High Resolution Fiber Fed Spectrograph
John M. Brewer, Matthew Giguere, Debra A. Fischer
The CHIRON spectrometer is a new high-resolution, fiber-fed instrument on the 1.5 meter telescope at Cerro Tololo Inter-America Observatory (CTIO). To optimize use of the instrumen…
IVOA Recommendation: Sky Event Reporting Metadata Version 2.0
Rob Seaman, Roy Williams, Alasdair Allan +12
VOEvent defines the content and meaning of a standard information packet for representing, transmitting, publishing and archiving information about a transient celestial event, wit…
