Gemini South Wind Test Data and Analysis

GEMINI SOUTH WIND TEST DATA CODE ID = p00045ho

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 = 45 degree (45 degree Elevation)
Upwind gate : half open
Downwind gate: open
