XAS data in Transmission (I0 and I1 ion chambers)

This is an example of a XAS data in transmission mode at SPring-8 BL0101.

As you can find, the Angle(c), Angle(o), time, "1", "2" columns (mode) are converted into energy_requested, energy_attained, time, i0, i1 columns.

Then, you must choose energy_attained as Energy, i0 as Numerator, i1 as Denominator, select Natural log checkbox.

Because a XAS spectrum in transmission mode is formulated in

\begin{equation*} \mu = - \ln{ \frac{I_1}{I_0} } = \ln{ \frac{I_0}{I_1} } \end{equation*}

The Angle(c), Angle(o), time, "1", "2" columns are converted into energy_requested, energy_attained, time, i0, i1 columns.

You must choose energy_attained as Energy, i0 as Denominator, i1 (=if) as Numerator, unselect Natural log checkbox.

Because a XAS spectrum in fluorescence mode is

\begin{equation*} \mu \propto \frac{I_f}{I_0} \end{equation*}

The Angle(c), Angle(o), time, etc columns are converted into energy_requested, energy_attained, time, i0, i1, 6, 7, 8... columns.

You should choose energy_attained as Energy, "23" as Denominator, "i1", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", as Numerator, unselect Natural log checkbox.

Because a XAS spectrum measured in fluorescence mode with a 19ch SSD is

\begin{equation*} \mu = \frac{I_f}{I_0} = \frac{i0+i1+"6"+\ldots+"22"}{"23"} \end{equation*}
