<p class="MsoNormal">Hello!<o:p></o:p></p>
</div>
<p>To phase markers I cannot tell much. Usually they are there (maybe only after refinement of the phase?).<o:p></o:p></p>
<p>I also requested a feature concerning the background once. I cannot estimate if it is very complex to do so. One option available is to define anchor points that are used to calculate the bg-function. That can be tedious and doesn't solve the issue of the
bad adaptation..<br>
There is also a possibility to load a dataset from a file as background, if there is e.g. amorphous signal.<o:p></o:p></p>
<p>Best,<br>
Phil<o:p></o:p></p>
