+/* Adding new band filters (see also Iwave.h):
  *
+ * Note: the spectral range ranges 250 to 4000 nm (see Iwave.h) which is 
+ *   4000-250=3750nm, and (4000-250)/1500=2.5. Hence, the resulting step 
+ *   size is 2.5 nm in the ffu.s array.
+ *
  * o bands are defined by their discrete filter function
+ * o to compute a band position in the 1500 slots of ffu.s array, start
+ *   with 250nm using 2.5nm increments. The result is the starting index
+ *   for the spectral band.
  * o 1500 is the number of wavelength spectral description slots.
  *   - a 'for' loop fills up the slots with 0
  *   - then the ffu.s array is filled with each of the spectral bands data one after the other.
+ *     Example Lsat TM: (435-250) / 2.5 = 74
+ * o add iwave value, also in Iwave.h
+ * o add to GeomCond.cpp and GeomCond.h
