Early spectral evolution of Nova Sgr 2004 (Ederoclite+, 2006)

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)

(4 data files).
