    Thanks for another great video of CasaXPS!
    I have a question regarding the SB(0) prefix background: is there any place where I can read about it? I've seen it used in some of your videos, but I am not able to find a thourough description of how to use it, how to constrain it, how to offset it depending on which kind of material I have, etc.

      The formal definition of the SB(0) modifier to a line shape is published in the paper:
      Smith, Emily, et al. "Modification of conventional peak shapes to accurately represent spectral asymmetry: High-Resolution X-ray photoelectron spectra of [C4C1Pyrr][NTf2] and [C8C1Im][NTf2] ionic liquids." Applied Surface Science 611 (2023): 155314.
      and discussed in the paper:
      Fairley, Neal, et al. “Practical guide to understanding goodness-of-fit metrics used in chemical state modeling of x-ray photoelectron spectroscopy data by synthetic lineshapes using nylon as an example.”Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films 41(1) (2023); doi: 10.1116/6.0002196

      I am not sure what is meant by SECO region. Would you please provide more information about your application?

      I meant secondary electron cut off region for a work function as @al mentioned.

      The secondary electron cutoff can be estimated using other means. The following video looks at one possible solution. ua-cam.com/video/UXQMrPgBVvs/v-deo.html

    Thank you for your video!!
    I am a big fan of casaXPS from Korea.
    I have a question. Is there a way to remove UV beta peak of raw UPS data in casaXPS?
    Generally, UV light is not monochromatic so sometimes researchers get rid of UV beta spectrum in UPS spectrum!
    Sincerely,
    Seunghwan Kim

      I have added a short video to explain how to remove satellite signal from UPS data: ua-cam.com/video/SvkB77G4RWo/v-deo.html
