The European Solar Telescope (EST) is a project of a new-generation solar telescope. It has a large aperture of 4 m, which is necessary for achieving high...
Results of site testing using an aerosol, backscatter lidar at the Roque de los Muchachos Observatory
Because of the high quality of its sky, the Roque de los Muchachos Observatory (ORM), located on the island of La Palma in the Canary Islands, is home to many...
Retrieval of solar magnetic fields from high-spatial resolution filtergraph data: the Imaging Magnetograph eXperiment (IMaX)
Context. The design of modern instruments does not only imply thorough studies of instrumental effects but also a good understanding of the scientific analysis...
Sampling and Characterization of the Turbulence Vertical Distribution. Statistics of SCIDAR Profiling
Unlike the trial procedures, a reliable characterization of the vertical turbulence distribution on a site should be based in unbiased statistical sample...
Sloan Digital Sky Survey IV: Mapping the Milky Way, Nearby Galaxies, and the Distant Universe
We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic...
The prototype SONG node, SONG-OT, is currently being installed and tested at Observatory del Teide on Tenerife. SONG will be a global network of 1-m robotic...
SOPHISM: An End-to-end Software Instrument Simulator
We present a software simulator for the modeling of astronomical instrumentation, which includes platform effects and software processing. It is an end-to-end...
Spectro-polarimetry in the era of large solar telescopes
This paper discusses some of the challenges of spectro-polarimetric observations with a large aperture solar telescope such as the ATST or the EST. The observer...
