- Status changed from verifying to reopened
- Resolution fixed deleted
A couple of usability things:
- WorkspaceIndex should allow a list of indices rather than all or one.
- Between the wiki and the mouse-over text, the use of SigmaConstant is unclear.
- Does the fit window parameter need to be the same for all spectra (I think so)? Make this clear in the wiki.
- Wiki should give a brief description of the output table
- The output table columns should get slightly renamed: peak_min->peak_min_index and peak_max->peak_max_index. This would clarify what they are.
