Cumulative Reports
[groupbox]
Larger. Use to report the total volume found in pores larger than the
current pore size.
Smaller. Use to report the total volume found in pores smaller than

Pores [groupbox]
Enter the minimum and maximum diameter (radius or width) of pores
to include in the BJH reports.
Fraction of pores open at both ends. This field is not available for
the BJH Desorption Report Options window.
During adsorption calculations, the analysis program assumes that
all pores are closed at one end. Occasionally, a percentage of pores
may be open at both ends causing disagreement in the adsorption
and desorption data or in the values for total volume and total BJH
pore volume. Enter the fraction of pores open at both ends to
compensate for this error.
