All Tables

Table 1: General properties of the data. The dates of observations and the corresponding data sets (numbers usually refer to individual nights; for exceptions see text) are presented in Cols. 2 and 3, respectively. Column 4 gives the total number of spectra available for the analysis, Col. 5 their spectral resolution (FWHM), Col. 6 the telescope used for the observations, and the last column lists references concerning the previous publication of the data sets.
Table 2: Radial-velocity parameters for H $\alpha$ as derived by the analysis of the diagnostic diagram. Column 2 gives the FWHM of the Gaussians used for the diagram, Col. 3 the critical separation, Cols. 4 and 5 contain the resulting semi-amplitude and the error of the zero phase, respectively. The $\gamma$ parameter is not listed, as it reflects more the wavelength calibration process than a real physical parameter.
Table 3: Isolated emission features detected in the individual data sets, which here appear sorted with increasing equivalent width. Columns 2 to 4 give basic parameters of the systems, i.e. the period, the inclination, the mass ratio q = M₂/M₁, and the (normal) outburst recurrence time, except for RZ Leo and WX Cet, which show only superoutbursts. These parameters were taken from the Ritter & Kolb (1998) catalogue except where indicated. Columns 5 and 6 contain the data set specific information on the equivalent width of the H $\alpha$ emission line and the accretion state during the observations (d = decline, q = quiescence), respectively. The x-velocities in Cols. 7 and 8 refer to the emission maxima in the respective halves of the Doppler maps, other emission regions are denoted by their identification. The presence of a feature is indicated by "+'', its absence by "-'', uncertain ones by "?'', and very uncertain ones by "??''.
