Is Arcturus a well-understood K giant? Test of model atmospheres and potential companion detection by near-infrared interferometry
T. Verhoelst, P. J. Bordé, G. Perrin +8
We present near-IR interferometric measurements of the K1.5 giant Arcturus (alpha Bootis), obtained at the IOTA interferometer with the FLUOR instrument, in four narrow filters wit…

The calibration of interferometric visibilities obtained with single-mode optical interferometers. Computation of error bars and correlations
G. Perrin
I present in this paper a method to calibrate data obtained from optical and infrared interferometers. I show that correlated noises and errors need to be taken into account for a…

Subtracting the photon noise bias from single-mode optical interferometer visibilities
G. Perrin
I present in this paper a method to subtract the bias due to source photon noise from visibilities measured with a single-mode optical interferometer. Properties of the processed n…
