Comparison of Reconstruction and Control algorithms on the ESO end-to-end simulator OCTOPUS
Extremely Large Telescopes are very challenging concerning their Adaptive Optics requirements. Their diameters, the specifications demanded by the science for...
Comparison of Solar Oscillation Data Obtained from a Study of the NA and K Fraunhoffer Absorption Lines
Two independent resonant scattering spectrometers, one using a sodium and the other a potassium vapour cell, were operated simultaneously at the same site. Due...
Comparison of the aerosol index from satellites and the atmospheric extinction coefficient above the Canarian Observatories
Satellite data measuring aerosols over the Canary Islands need to be correctly interpreted in accordance with the spatial resolution and spectroscopic channels...
Comparison of the Calibrated MDI and GOLF Signals. IV. p-Mode Energy Budget
The energy calculation of the p-modes requires accurate estimates of both amplitudes and linewidths. These parameters can be derived from a suitable model used...
Comparison of the Calibrated MDI and GOLF Signals. V. The Low Frequency p-Modes
Low-frequency p-modes have relatively small amplitudes and are set against the background of granulation on the solar surface. In this work, the calibrated...
Comparison of the Ionized Gas and Stellar Kinematics in the Circumnuclear Regions of Seyfert Galaxies
Integral-field spectroscopy techniques are ideal to study objects of complex morphology and kinematics such as the circumnuclear region of AGN. We have obtained...
