get_seg_scale.RdIn order to identify the congruent registration position of a basis segment,
the length of the basis segment will be doubled to compute the correlation curve.
get_seg_scale computes the increased segment, which has the same center
as the basis segment.
get_seg_scale(segments, nseg, out_length)list with basis segments and their corresponding indices in the original profile, obtianed by get_segs()
integer. nseg = 3: increase the length of the third basis segment.
integer. The length of the enlarged segment
list consisting of
aug_seg: the increased segment
aug_idx: the corresponding indices in the profile
