uvby photometry & radial velocities of R 81
Listed in IVOA Registry (Virtual Observatory)
File table1.dat contains the photometric uvby data of the eclipsing binary hypergiant R81 (B2.5 Ia-O) of the Large Magellanic Cloud.
Description
The data have been obtained with the Danish 50 cm telescope at ESO, La Silla, and cover more than one orbital cycle of 74.59 days. File table2.dat contains radial velocity measurements of photospheric lines of this star.
The spectra have been obtained simultaneously with the photometry. The Feros spectrograph at the ESO 1.52m telescope was used. The quoted radial velocities are averages over the best photospheric lines.
