To each row of the rebinned spectrum, this command will apply the closest dispersion relation. If a one-dimensional dispersion relation was estimated,<I>e.g.</I> by averaging the rows of the arc spectrum before wavelength calibration, the command <TT>REBIN/LONG</TT> will apply this unique dispersion relation all over the spectrum. <BR> <BR> Midas...> <TT>REBIN/LONG in out</TT> <BR> <BR> rebins each row of the input frame <B>in</B> separately, using the dispersion coefficients stored in table <B>COERBR</B>.
