Caution: the gas rate value is quoted on the x-axis, the related network pressure is quoted on the y-axis (pres-
sure value in the combustion chamber is not included). To know the minimum pressure at the gas train inlet,
necessary to get the requested gas rate, add the pressure value in the combustion chamber to the value read on
the y-axis.
