The non-ideality correction can be used if there is no com-
pressibility table for the gas you are using or if you want to
match existing data.
This factor adjusts the ideal gas law for calculating the
quantity of gas in the cold free space. Most gases are nearly

the correction is most important. If you choose this option,
the field for the Non-ideality factor is enabled, allowing
you to enter a value.
