Table 1: Basic observations parameters of the observed stars.
Table 2: Rotational velocities for (some of) our program stars. LHS 428 is omitted because it is a double star and could not be separated. LHS 6158 even seems to be a triple system. GJ 229A is saturated in the red arm. Prox Cen was used as template for UV Cet, FN Vir and GL Vir in the blue arm. All measurements in ${\rm km~ s^{-1}}$ .
Table 3: Properties of the Ti II and the Fe XIII line during the flare on LHS 2076. Given are the amplitude (in electrons), the central wavelength and half width $\sigma$ of each line for the best fit. For the 3380.28 Å line no error estimation for the half width was possible due to the low signal to noise ratio.
Table 4: Properties of the Ti II of UV Cet measured with CORA using a broad and a narrow component simultaneously. Given are always the values for the narrow (first) and the broad component (second).
Table 5: List of the line fluxes, central wavelength and half widths $\sigma$ measured with CORA. Due to the signal to noise ratio the computation of the error of the half width could not be done for every line.
