AIRMASS CALC is a very simple program, or if you like quite a modern one, a tool which does only one thing: it computes Airmass and Scintillation which satisfies different criteria.
AIRMASS CALC can rewrite the report AAVSO with adding the airmass in the correct column.
Many thanks to Arne Henden (AAVSO Director) and Aaron Price (Technical Assistant, Technology) for their help and encouragement.
