Gemini South Wind Test Data and Analysis

GEMINI SOUTH WIND TEST DATA CODE ID = p04560cc

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

Wind attack direction to SLIT = 045 degree Azimuth angle
Zenith angle = 60 degree (30 degree Elevation)
Upwind gate : closed
Downwind gate: closed
