Hi Mark,

The presently implemented DOatmosphere.h interface is close to TELCAL's 
ATM-0.1 and can be accessed using atmosphere.g.  There isn't a version 
number on the latest TELCAL ATM.  As I have commented before it is 10 
times bigger now so they may have been thinking along those lines when 
they relabeled the old version from ATM to ATM-0.1 ;-).
