XRT Calibration Meeting 2022.

Topics from MSU

1. Results of the stray light measurements of 2021 eclipse season (AT)
   Results of the stray light measurements of 2021 eclipse season (AT)

   • "stray light" at MSU = "light leak" at SAO
   • visible light component contaminated in X-ray images.
   • caused by ruptures developed on the surface of pre-filter.

2. Update of XRT response functions with Chianti DB ver.10.0. (AT)

   [Temperature response func.] = [Factor(geometrical, etc.)] * [Model Solar Spectra] # [XRT Effective Area]
              (T)                                                       (T, λ)                   (λ)
   

   • this report is about the "Model Solar Spectra" part.
   • the "Effective Area" part is covered by the topic 3 (below).
