Results from disentangling around the Li i 6708 Å line of Capella from the observations indicated in Table 2. a) Result for the determined situation with one spectrum per two consecutive quadratures; b) as above but with an additional spectrum at conjunction, which is the minimal necessary set of required data; c) two spectra per two consecutive quadratures. This set yields only a determined system, which can distinguish better between noise and the signal of the components; d) all five spectra yield a minimum overdetermined system with good noise reduction.
