STARE operations experience and its data quality control
The STARE instrument was the first to detect the transits of an extrasolar planet in 1999. To date it has performed one of the longest running searches for...
Statistical structure of the atmospheric optical turbulence at Teide Observatory from recalibrated generalized SCIDAR data
The characterization of the optical turbulence structure at an astronomical site requires a proper data base of the refractive-index structure constant, ?. Our...
Statistics and analysis of high-altitude wind above the Canary Islands observatories
High-altitude wind has been recently proposed as an important parameter to be taken into account for astronomical site selection. We present here comprehensive...
