       Differential rotation parameters~$A$, $B$, and~$C$
       from Eq.~(15) for the interactive method, without the height
       correction. The sidereal parameters
       and their standard errors~($M$) are expressed in deg/day for
       three cases (see remarks). Both solar hemispheres are treated
       together and the number of tracers $n=1179$ (after the velocity filter
       was \mbox{applied}).
