Abstract

We present high spatial resolution observations in the mid-infrared of the Sakurai's object (V4334 Sgr) obtained with the Very Large Telescope Interferometer (VLTI) of ESO's Paranal Observatory and MIDI, the MID-infrared Interferometric recombiner. MIDI combines the light of two telescopes and provides spectrally resolved visibilities in the N band atmospheric window. The optical interferometry data are used in the paper from Chesneau et al. entitled "A dense disk of dust around the born-again Sakurai's object" and are available in OI-FITS format. The data were recorded in June 2007 under rather good atmospheric conditions and were reduced with the EWS package. The data set contains 6 spectrally dispersed calibrated visibilities and 6 differential phases. The files include all visibility data recorded from these observations as well as all the characteristics concerning the observations in the form of two OI-FITS files, for each night of observation. The log of the observations is shown in Table 1. The data products are stored in the FITS-based, optical interferometry data exchange format (OI-FITS), described in Pauls et al. (2005PASP..117.1255P). The OI Exchange Format is a standard for exchanging calibrated data from optical (visible/infrared) stellar interferometers. The standard is based on the Flexible Image Transport System (FITS), and supports storage of the optical interferometric observations including visibilities and differential phases. Several routines to read and write this format in various languages can be found in: Webpage http://www.mrao.cam.ac.uk/~jsy1001/exchange .
