overview

• orange widgets
  • Autobk
    • make Rbkg, kmin, kweigh QDoulbeSpinBoxes
  • XFTF
    • make Kmin, kmax, dk, dk2 floats
• noise:
  • make Estart and Eend relative to the Edge energy. Default values can be the same as for norm range in autobk.
  • display both normalized an raw mean noise average
  • plot verticals lines for eMin and eMax
  • rename "window size" by "number of points"
  • add labels to X and Y markers
• XFTF: make k_max optional. If set must be in absolute. If not then take it at 90%.
