Resampling with the Row-by-Row Solution

The command REBIN/LONG can be used to apply the row-by-row dispersion solutions. To each row of the rebinned spectrum, this command will apply the closest dispersion relation. If a one-dimensional dispersion relation was estimated,e.g. by averaging the rows of the arc spectrum before wavelength calibration, the command REBIN/LONG will apply this unique dispersion relation all over the spectrum.

rebins each row of the input frame in separately, using the dispersion coefficients stored in table COERBR. The limits and step in the wavelength space are estimated automatically by the command CALIBRATE/LONG and can be checked with:
