hi Reza<br>
<br>
[a.u.] means arbitrary units. It is conventional to use this when the <br>
measurement is not direct (like counts/s) but relative, which is often the <br>
case in synchrotron experiments where the measurement is normalized versus <br>
an incident flux of x-rays.<br>
<br>
Cheers,<br>
<br>
