Preset calculations are performed on the fly, as requested by user.
Calculation is only performed when condition equation is true, otherwise the failed condition value is output
Plots using a Langley calculation will be plotted versus airmass (instead of time) and will also include a linear fit with slope & intercept.
Wind Direction Deltas are special cases that go beyond the equations listed above to keep the data in the 0 to 180 degree realm.
