2. Click the icon below the browser and select Misc/Spin Asymmetry for VLEED. The
calculation will run on the data. Figure 8 shows some results of this calculation.
The input parameters allow you to alter the operation. The table below lists all the input
parameters for the Spin Asymmetry for VLEED operation. After setting the parameters, click
Apply to run the operation with the new settings.
Table 2. Input parameters for the spin asymmetry calculation
Input parameter Value
Asymmetry Cycle The name of the step profile used for the magnetization of the
target. This is the same as the name shown in the Experiment
Editor.
Summation Cycle You can leave this setting as "Loop". If a loop is used for a
number of iterations of the experiment, this is taken into
account. In the case of no loop being used, this section is
ignored.
Asymmetry Cycles Size This should be the number of cycles in the magnetization step
profile that is included in the Experiment Editor.
Asymmetry Forward Direction This parameter, together with Asymmetry Backward Direction,
determines which scan measures positive spin and which
negative. One parameter must be OFF, the other ON. If you
change these values, the result of the calculation will be
reflected around the horizontal axis.
Asymmetry Backward Direction See Asymmetry Forward Direction above
