Lumma stability

For improper scales, Lumma's impropriety factor is defined as the portion of the spectrum which is more than singly covered. For scales which are proper or strictly proper, there are no overlapping intervals and the impropriety is therefore always zero.

[from Manuel Op de Coul, Scala file "tips.par; view in Scala with command "SHOW DATA"]
