Magnetic classifications of sunspots based on the Zürich/McIntosh-system:
Classification Values (C.V.) derived by Kjell Inge Malde (15 Aug 1981) is:
"A 'sunspot count' derived using weighting of
Zürich (Modified) McIntosh classifications":
"The 'C.V.' intends to measure the variety of sunspot region classifications
with respect to their ability of survival, typical life styles, complexity,
structure, polarity, size and elongation on the solar disk."
