GEMINI SOUTH WIND TEST DATA CODE ID = c00030co

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 : closed
  • Downwind gate: open

At +X: Resultant 2.1 m/s
U= -.1 V= 1.5 W= .2
Resultant V_RMS = 1.3

At -X: Resultant 1.0 m/s
U= .0 V= -.6 W= -.1
Resultant V_RMS = .5

At -Y: Resultant 1.0 m/s
U= .4 V= -.4 W= -.5
Resultant V_RMS = .4

At M2: Resultant 4.7 m/s
U= 1.7 V= 4.0 W= .8
Resultant V_RMS = 1.4

At Dome: Resultant 10.4 m/s
