  • Improvement of the Helioseismic and Magnetic Imager (HMI) Vector Magnetic Field Inversion Code 
    Grinon Marin, Ana Belen; Pastor Yabar, Adur; Liu, Yang; Hoeksema, J. Todd; Norton, Aimee A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Abstract A spectral line inversion code, Very Fast Inversion of the Stokes Vector (VFISV), has been used since 2010 May to infer the solar atmospheric parameters from the spectropolarimetric observations taken ...
  • On Identifying and Mitigating Bias in Inferred Measurements for Solar Vector Magnetic-Field Data 
    Leka, K.D.; Wagner, Eric L.; Grinon Marin, Ana Belen; Bommier, Véronique; Higgins, Richard E. L. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The problem of bias, meaning over- or under-estimation, of the component perpendicular to the line-of-sight [B⊥] in vector magnetic-field maps is discussed. Previous works on this topic have illustrated that the problem ...
