The program tables, which is given in several languages, produces four atmosphere tables:

  1. a table is US units from 0 to 280000 ft. by 5000 ft.
  2. a table in SI units form 0 to 86 km by 2 km
  3. a table in US units from 0 to 65000 ft. by 1000 ft., and
  4. a table in SI units from 0 to 20 km by 0.5 km.

The goal is to produce exactly the same text in all programs, but there are small differences.
