Description
We present the largest data base so far of atmospheric optical turbulence profiles [197 035 individual C2N(h)] for an astronomical site, the Roque de los Muchachos Observatory (La Palma, Spain). This C2N(h) data base was obtained through generalized SCIDAR observations at the 1-m Jacobus Kapteyn Telescope from 2004 February to 2009 August, obtaining useful data for 211 nights. The overestimation of the turbulence strength induced during the generalized SCIDAR data processing has been analysed for the different observational configurations. All the individual C2N(h) have been recalibrated to compensate for the errors introduced during data treatment. Comparing the results from profiles before and after the recalibration, we analyse its impact on the calculation of relevant parameters for adaptive optics.

    Euclid preparation. XXXVI. Modelling the weak lensing angular power spectrum

    This work considers which higher order modeling effects on the cosmic shear angular power spectra must be taken into account for Euclid. We identified the relevant terms and quantified their individual and cumulative impact on the cosmological parameter inferences from Euclid. We computed the values of these higher order effects using analytic

    Euclid preparation. XXXVII. Galaxy colour selections with Euclid and ground photometry for cluster weak-lensing analyses

    Aims: We derived galaxy colour selections from Euclid and ground-based photometry, aiming to accurately define background galaxy samples in cluster weak-lensing analyses. These selections have been implemented in the Euclid data analysis pipelines for galaxy clusters. Methods: Given any set of photometric bands, we developed a method for the
