Chopping between the source and 1 or 2 background positions was an ISOPHOT observing mode for faint source photometry. More than 7000 observations of this type...
Analysis of low frequency signal with the GOLF experiment: methodology and results
Four years of GOLF velocity time series have been used to study the low frequency part of the solar spectrum below 1.5 mHz. This paper discusses the methods...
Analysis of rotational frequency splittings sensitive to the rotation rate of the solar core
Updated solar frequency splitting measurements suggest a slight decrease of the rotation rate below 0.25 Rsolar and, albeit preliminary, rule out a core...
Analysis of Stellar Spectra from the Century Survey
We describe new methods of analysis that have been developed in order to make optimal use of the stellar spectral data obtained during the course of follow-up...
Analysis of surface deformation during the eruptive process of El Hierro Island (Canary Islands, Spain): Detection, Evolution and Forecasting.
The surface deformation has been an essential parameter for the onset and evolution of the eruptive process of the island of El Hierro (October 2011) as well as...
Analysis of the chromosphere and corona of low-activity early-M dwarfs
While most of the exoplanets have been found orbiting around solar-type stars, low-mass stars have recently been recognized as ideal exo-life laboratory...
Analysis of the Difference Light Curve of the Gravitational Mirage QSO 0957+561
From optical data of Q0957+561 for 1995/1996 seasons (in the g band) and 1996/1997 seasons (in the R band) they are derived upper limits on the amplitude of the...
