... Finally, the individual observations themselves are reduced, using the parameters from the extinction solution. ... That is, the extinction solution can in principle produce results if we observe extinction star 1 only in passband A and star 2 in passband B on night 1, and star 1 only in passband B and star 2 in passband A on night 2. ... Even if the passbands are linked by color terms in the extinction, the solution is possible, because we do obtain mean colors for each star. ...
