Extracting Radial Velocities of A- and B-type Stars from Echelle Spectrograph Calibration Spectra

Juliette C. Becker, John Asher Johnson, Andrew Vanderburg +1

We present a technique to extract radial velocity measurements from echelle spectrograph observations of rapidly rotating stars ($V\sin i\gtrsim 50$ km s${}^{-1}$). This type of me…
