The gas consumption was measured in te beamtime 1999 over 1 week. The Excel file can be downloaded. The gas pressure as a function of time is plotted here and can be downloaded as PS-file.
The linear fit of the data points give us a function: p(t)[bar] = 0.36 t[days] + 5.47 [bar]. This means, that we have decrease in the bottle pressure (== gas consumption) of 0.36 bar / d.
