   \fu~$= 4.7126$~\cd, \fd~$= 2.2342$~\cds and \ft~$= 4.671$~\cds calculated
   from the $uvby$ time-series of V2104~Cyg by means of a triperiodic least-squares fit. For each filter the mean
   magnitude difference is given together with the rms, of the residuals. The last row indicates the calculated ($S/N=4$)-level at \ft~$= 4.671$~\cd. Phase = 0 corresponds to $T_0= 2~453~647.3034$.}
