        _diffrn_reflns_class_description
               1580 0.551 6.136 0.015 'Main' 'm=0; main reflections'
               1045 0.551 6.136 0.010 'Sat1' 'm=1; first-order satellites'

Example 1 - example corresponding to the one-dimensional incommensurately modulated structure of K~2~SeO~4~. Each reflection class is defined by the number m=sum|m~i~|, where the m~i~ are the integer coefficients that, in addition to h,k,l, index the corresponding diffraction vector in the basis defined for the reciprocal lattice.
