  Short update of hypernuclear database website
  
  Sprecher: Philipp Eckert (KPH Mainz)
  Status of hypernuclear database website:
  
  - new features implemented:
  
  \Delta B _\Lambda \Lambda
  
  Energy levels of exited states (gamma transitions)
  
  collection of data for ^4_\lambda H (binding energies and lifetime)
  
  ability to add papers without data for completeness of database
  
  ^3_\lambda H: STAR2021 value added to lifetime, only small influence
  
  - Templates for data collections have been sent to multiple people at different places and will be spread more

  Update of analysis of undulator data
  
  Sprecher: Pacal Klag (KPH Mainz)
  update of data analysis of undulator data analysis for energy measurement of MAMI:
  
  aim relative energy resolution 10^4
  
  already in the slightly above 10^-4 before fine tuning
  
  fine tuning of the fits of difraction data
  
  compensation of negative offset in data required to improve the fit of the wavelength
