All Tables

Table 1: Portion of Table 1, available only electronically at the CDS, to illustrate its content. The quoted error is the Poisson error and the last column provides identification of the telescope (see details in Sect. 2.1).
Table 2: Journal of spectroscopic observations.
Table 4: Heliocentric velocity, velocity span at half maximum, equivalent width, and integrated absolute flux (in units of 10^-13 erg cm^-2 s^-1) of the emission component and pre-maximum, principal and diffuse enhanced absorption systems for the H $\alpha$ profiles shown in Fig. 6 (and in addition for the H $\alpha$ profile of Apr 27.09, 2006 not shown in Fig. 6 to save space).
Table 5: Radial velocity and equivalent width of the Orion absorption system as observed in the HeI 6678 Å line.
Table 6: The optical depth, electron temperature and mass of neutral oxygen in NCyg06 from the [OI] 5577, 6300 and 6364 Å emission lines. The listed epochs are those of the spectra showing the 5577 Å line in emission.
Table 7: De-reddened emission line ratios relative to H $\beta$ as observed on the Jan. 20, 2007 spectrum of Nova Cyg 2006 and as predicted by the CLOUDY model detailed in Table 8.
Table 8: Parameters of the CLOUDY model best-fitting the de-reddened emission line ratio of Table 7. From top to bottom: temperature and radius of the central black-body source, inner and outer radii of the emitting shell, hydrogen density at inner and outer radii, electronic density at the inner and outer radii, ratio of the filled to vacuum volumes, element abundances relative to solar.
Table 9: Mass-fraction abundances of measured elements in Nova Cyg 2006 and, for reference, in the Sun.
Table 3: Photometry of the progenitor of Nova Cyg 2006 on photographic plates of the Asiago Schmidt Telescopes archive. This material is new and extends the coverage in time of the 1962-1984 archive material presented by Jurdana-Sepic & Munari (2006). The nova progenitor is always below the plate magnitude limit, which is given in column seven, with respect to the photometric sequence calibrated by Frigo et al. (2006).
