Building stack lists

The stack_buildlist screen (Fig. 10) lets you define the set of files that comprise a stack. Often times you might take one image at an absorbing energy (for example, 288 eV) as the template, and then start the stack from 284 eV up to some higher energy. You can then identify the stack from seeing a long list of files with identical pixels, with one file at 288 eV first, and then a series of files at 284.0, 284.2, 284.6 eV and so on. Once you've identified the first filel, click on Set as first. Now go and find the last file of the stack from that day, and click on Set as last followed by Add first $\rightarrow$ last to list. If the stack ran overnight, you can then select the first file of the following day and click on Set as first, select the last file and click on Set as last, and again click on Add first $\rightarrow$ last to list. In this fashion you can build a list that spans more than one day (e.g., add 16aug050-16aug083 and 17aug001-17aug035 all into one list). When the list is complete, save it to a .sl file.

Figure 10: The stack_buildlist widget. In this widget, you pick a starting and ending files, and then add them to a list of files that belong to a stack. You can repeat the addition process, so that you can combine files taken one night with those which continued the next morning.
