Terry Girard

Research Scientist

Research Interests

My time and interests are split between a number of astrometric projects:

  • the Southern Proper Motion (SPM) program, which is a southern-sky absolute proper-motion survey,
  • the determination of absolute motions/orbits of Milky Way globular clusters and satellite systems,
  • HST-based measurement of the internal velocity distribution within globular clusters,
  • CCD observations of southern NEO minor planets,
  • precise measurement/monitoring of the solar radius with the SDS instrument,
  • particpation in a SIM key project to calibrate the Pop II age and distance scales.
