The PRIMA Fringe Sensor Unit (2009)

Sahlmann, Johannes, Menardi, Serge, Abuter, Roberto, Accardo, Matteo, Mottini, Sergio, Delplancke, Francoise

The Fringe Sensor Unit (FSU) is the central element of the Phase Referenced Imaging and Micro-arcsecond Astrometry (PRIMA) dual-feed facility and provides fringe sensing for all observation modes,...

Post-processing the VLTI fringe-tracking data: First measurements of stars (2008)

Bouquin, Jean-Baptiste Le, Abuter, Roberto, Haguenauer, Pierre, Bauvir, Bertrand, Popovic, Daniel, Pozna, Ester

At the Very Large Telescope Interferometer, the purpose of the fringe-tracker FINITO is to stabilize the optical path differences between the beams, allowing longer integration times on the...

New Photometry and Spectra of AB Doradus C: An Accurate Mass Determination of a Young Low-Mass Object with Theoretical Evolutionary Tracks (2007)

Close, Laird M., Thatte, Niranjan, Nielsen, Eric L., Abuter, Roberto, Clarke, Fraser, Tecza, Matthias

We present new photometric and spectroscopic measurements for the unique, young, low-mass evolutionary track calibrator AB Dor C. While the new Ks photometry is similar to that previously published...

Very high contrast IFU spectroscopy of AB Doradus C: 9 mag contrast at 0.2" without a coronagraph using spectral deconvolution (2007)

Thatte, Niranjan, Abuter, Roberto, Tecza, Matthias, Nielsen, Eric L., Clarke, Fraser J., Close, Laird M.

We present an extension of the spectral deconvolution method (Sparks & Ford 2002) to achieve very high contrast at small inner working radii. We apply the method to the specific case of ground based...

The SINFONI pipeline (2007)

Modigliani, Andrea, Hummel, Wolfgang, Abuter, Roberto, Amico, Paola, Ballester, Pascal, Davies, Richard, ...

The SINFONI data reduction pipeline, as part of the ESO-VLT Data Flow System, provides recipes for Paranal Science Operations, and for Data Flow Operations at Garching headquarters. At Paranal, it is...
