Description
The proper characterisation of the turbulence structure in an astronomical site requires an statistical study of the refractive-index structure constant Cn2(h). Our team is monitoring the Cn2(h) profiles since 2002 at the Teide and Roque de los Muchachos observatories (Canary Islands, Spain) with the g-SCIDAR technique. We have compared the turbulence profiles obtained with the radiosonde simultaneous profiles and with the NCEP I reanalysis maps at different levels. We show that turbulence measured at both observatories (being at 160km distant) correlate with the radiosonde data and may be explained through the atmospheric conditions in a synoptical scale. Hence, the statistical predominance of synoptical scaled phenomena may explain the similarity found in the monthly average profiles obtained at both observatories.

    ANDES, the high resolution spectrograph for the ELT: science goals, project overview, and future developments
    The first generation of ELT instruments includes an optical-infrared high resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion Echelle Spectrograph). ANDES consists of three fibre-fed spectrographs ([U]BV, RIZ, YJH) providing a spectral resolution of ∼100,000 with a minimum simultaneous wavelength

    ANDES, the high-resolution spectrograph for the ELT: UBV spectrograph preliminary design
    We present the design of the ANDES UBV module, the bluest spectrograph of the ANDES instrument. It is a fiber-fed high resolution, high stability spectrograph, which will be installed on the ELT-Nasmyth platform to minimize blue fibre losses from the focal plane to the spectrograph. In this paper we present the status of development of the
