Yale Doppler Diagnostic Facility
The Yale Doppler Diagnostic Facility (YDDF) is a test bench to investigate instrumental effects on high resolution spectra used in Doppler planet searches. We will be able to reproduce different spectrograph configurations and environmental conditions (like temperature and pressure). Additionally, a seeing simulator is planned to realistically simulate air turbulence and its effect on fiber coupling and spectrograph illumination stability. Major optical components are already in hand, and integration is planned for Q3 2011.
