In dual inlet mode, when calculating by hand the the raw ratios from raw
voltages output by Isodat, the hand calculated values match exactly the
values output by Isodat.
This not the case with Isodat output from the conflo. The hand
calculated values are close but not exact if the background is NOT
The mismatch increases if the backgrounds are subtracted, which would be
expected if raw ratios in Isodat are based indeed based on raw voltages.
But, from the conflo, why do the hand caculated raw ratios not match
exactly those from Isodat?
