Uday,
Have you tried creating a new performance curve feeding the "Raw Data
Points" from the Input Type dropdown menu? If not, I would say try to
create the Curve formula from excel (putting your Wetbuld depression and
the efficiency data and look up if it's Linear, quadratic, etc) then put
those values at a, b & c at Performance Curve Properties window.
The second method would, I guess, be more accurate.
Hope it helps,
Aru
