Description
We present results of our projected rotational velocities (V sin i) measurements of F, G and K giants obtained from the cross-correlation function (CCF) constructed from high signal to noise spectra. We also present the calibration of the HET/HRS cross-correlation function to determine accurate projected rotational velocities V sin i for slowly-rotating F-K giants.

    ANDES, the high-resolution spectrograph for the ELT: design of the adaptive optics system
    ANDES,the high resolution spectrograph for the ELT, will work both in seeing limited mode and with Adaptive Optics (AO) correction. ANDES-SCAO is a single conjugated AO system working with natural guide stars, feeding the IFU coupled to the YJH spectrograph. The main science goal of the ANDES AO mode is the characterization of the exo-planet

    Contrast optimization in wide-field AO
    In Solar Adaptive Optics (AO), it is common to work with a wide Field of View (FoV), which necessitates special control techniques to enhance system performance. Ground-Layer Adaptive Optics (GLAO) configurations lack sufficient degrees of freedom to correct altitude layers individually, resulting in an averaged correction across the entire FoV. In
