175. Solving a long-standing problem with the HMI data products

Contributed by Ana Griñón-Marín. Posted on March 21, 2022

For weak magnetic regions, HMI’s vector magnetic fields are known to give ambiguous signs in the east-west direction. A new inversion strategy is developed to address this problem, and the follow-up analysis shows that the new code improves HMI’s weak vector magnetic fields.
