AMBER Science Demontration Data

CPD-57 2874

Abstract

CPD-57 2874

The observations of CPD-572874 were acquired during a Science Demonstration Time (SDT) run, on the night of 25 February 2005, using the AMBER instrument on the VLTI in medium-resolution mode (R=1500). The three Unit Telescopes UT2, UT3, and UT4 were used. With an exposure time of 85ms, spectrally dispersed interferograms were recorded on the target and the calibrator (HD 90393). This allowed to obtain spectra as well as wavelength-dependent visibilities and a closure phase in the K band with a spectral resolution of R = 1500 between 2.09 and 2.24 micron (including the Br gamma line). The aim of this observation was to study the circumstellar envelope of this B[e] supergiant.

Description of the data set:
- Instrument: AMBER
- Configuration: 3 telescopes, medium resolution centered on Br Gamma line
- DIT: 85ms
