Astroclimatology of ESO Sites	ESO WIDE REVIEW M. Sarazin, April 2000, 6/10

Seeing Statistics at Paranal since UT1 first light: monthly average (0.90", upper curve), median (0.78", middle curve) and 5th percentile (0.43", lower curve). The dashed lines give the respective long term (89-95) site characteristics (median=0.66", 5 percentile=0.38"). Seeing is reconstructed from DIMM measurements taken at 6m above ground, at 0.5 micron and zenith.
