GEMINI SOUTH WIND TEST DATA CODE ID = c13560oo

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

  • Wind attack direction to SLIT = 135 degree Azimuth angle
  • Zenith angle = 60 degree (30 degree Elevation)
  • Upwind gate : open
  • Downwind gate: open

At +X: Resultant 7.0 m/s
U= -4.9 V= -4.7 W= -.8
Resultant V_RMS = 1.8

At -X: Resultant 1.4 m/s
U= .6 V= -.6 W= -.4
Resultant V_RMS = .6

At -Y: Resultant 1.2 m/s
U= .2 V= -.3 W= -.8
Resultant V_RMS = .5

At M2: Resultant 7.6 m/s
U= -5.9 V= -4.4 W= .6
Resultant V_RMS = 1.8

At Dome: Resultant 2.8 m/s
U= 1.0 V= -.3 W= 1.4
Resultant V_RMS = 1.1
