my note on your result

["Bernhard Lauss" <lauss@ill.fr>]

Dear Brendan,

I think I have screwed up yesterdays calculation.

Rethinking it today, I believe you have solved the oxygen puzzle
with your present analysis,

So given your numbers

            Yield EVH ppm    humidity (in atomic ppb)
low flux    450              1140

high flux   120              360

please confirm that these numbers now are correct

taking  delta_Y / delta_humidity = 330 / 0.780 = 423

comparing that to the common 397 in all our tables

this clearly indicates that everything is
consistent with literature, MuCAP does not have a problem
and we have been puzzled for the last 10 monthes
because Claude went too early skiing.

  good night, see you all soon

       Bernhard
