GEMINI SOUTH WIND TEST DATA CODE ID = t04560co

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: open

At +X: Resultant 5.8 m/s
U= -4.8 V= 2.4 W= 1.8
Resultant V_RMS = 1.1

At -X: Resultant 3.2 m/s
U= -2.7 V= -1.2 W= 1.0
Resultant V_RMS = .8

At -Y: Resultant 3.0 m/s
U= -2.5 V= -.7 W= .4
Resultant V_RMS = .9

At M2: Resultant 2.4 m/s
U= 1.0 V= -.6 W= 1.2
Resultant V_RMS = 1.1

At Dome: Resultant 4.2 m/s
U= -1.3 V= 1.3 W= -.3
Resultant V_RMS = 2.9
