[Simon, Pengbo]
Attached to this report are the XY maps and distribution histograms of the absorption coefficient from the Shinkosha #5((shown in the attached figure 1 and 2), and Shinkosha #6(shown in the attached figure 3 and 4), the color bar scale for the two maps is the same.
As can be seen, sample #6 has better absorption than sample #5, and we think this is due to the inhomogeneous of the absorption along the z-axis of the samples.
For these two samples, we choose the center of the z-axis. We can check our assumption by doing another XZ maps.
