GEMINI SOUTH WIND TEST DATA CODE ID = t00030oc

Average and RMS wind pressures and average wind velocities were calculated from the wind test in the following conditions:

  • Wind attack direction to SLIT = 000 degree Azimuth angle
  • Zenith angle = 30 degree (60 degree Elevation)
  • Upwind gate : open
  • Downwind gate: closed
