GEMINI SOUTH WIND TEST DATA CODE ID = p04560oo

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 : open
  • Downwind gate: open

At +X: Resultant 8.3 m/s
U= 7.7 V= -2.1 W= .9
Resultant V_RMS = 1.8

At -X: Resultant 10.0 m/s
U= 7.5 V= 5.8 W= 2.2
Resultant V_RMS = 1.9

At -Y: Resultant 5.7 m/s
U= 5.0 V= -1.0 W= -.8
Resultant V_RMS = 1.8

At M2: Resultant 3.7 m/s
U= 1.3 V= .9 W= .2
Resultant V_RMS = 2.5

At Dome: Resultant 16.7 m/s
U= 10.6 V= 9.1 W= 8.9
Resultant V_RMS = 1.5
