Hi Jens,

I have tried to duplicate isodat data as well (from dual inlet) and I am
very close to get the exact result (change in the 7th decimal place of the
delta value). It is not possible to change the significant numbers displayed
for the "intensities" (3) in the results (.did files), but if you look at
the plot below (on the same .did file), you can display a table with 6
decimal places for the signal. 

However, I'd very much like to know what precision Isodat is using for
intensities. 

What I wonder is whether the impossibility to duplicate Isodat calculation
is due to a lack of infomation on intensities, or due to the fact that there
are different steps involved from intensity to delta value, and Isodat might
round those numbers during the process (eg. delta1 and delta2 which are then
averaged to get the "true" delta value) 

Best regards,

Corentin
