Abstract:
We present optical and near-infrared spectral evolution of the
Galactic nova V5114 Sgr (2004) during few months after the outburst.
We use multi-band photometry and line intensities derived from
spectroscopy to put constrains on the distance and the physical
conditions of the ejecta of V5114 Sgr.
Description:
Data files of FEROS observations are given with four digits (referring
to month and day of observation) and an "f" indicating that that is a
FEROS observation.
Data files of observations carried out at Cerro Tololo are named with
four digits (referring to month and day of observation) and a "t"
indicating that these are CTIO observations.
Observations carried out with the NIRIS instrument are given in three
dat files. Although they were carried out on a single night, for
uniformity with the rest of the files, these data files are named with
four digits (referring to month and day of observation), an "n"
indicating that is a NIRIS observation and a letter indicating the
wavelength range ("o" for 500-1000nm , "b" for 800-1400nm and "r" for
1400-2500nm)
