Abstract:
We present echelle spectrophotometry of the Galactic H II region
S311. The data have been taken with the Very Large Telescope
Ultraviolet-Visual Echelle Spectrograph in the 3100-10400Å range.
We have measured the intensities of 263 emission lines; 178 are
permitted lines of H0, D0 (deuterium), He0, C0, C+, N0,
N+, O0, O+, S+, Si0, Si+, Ar0 and Fe0; some of them
are produced by recombination and others mainly by fluorescence.
Description:
The observations were made on 2003 March 30 with the UVES, at the VLT
Kueyen Telescope in Cerro Paranal Observatory (Chile). We used the
standard settings in both the red and blue arms of the spectrograph,
covering the region from 3100 to 10400Å.
