segm2(n)

choose the way the second segmentation is done in BCORR 3. This
feature is only useful with a polynomial approximation.

0 : without.
1 : interactive.
2 : automatic.

When you choose an interactive second segmentation, you have to
choose one or several areas with the WINDOW command to allow the
program to cut the correction in these areas if needed. The
automatic segmentation uses a window, WINSEGM2, and a threshold,
LEVELSEGM2.
