59. The HMI Vector Magnetic Field Synoptic Charts Contributed by Yang Liu. Posted on August 31, 2016 HMI now routinely produces vector magnetic field synoptic charts. This Nugget describes the data reduction procedures and the method chosen to resolve the 180-degree ambiguity in azimuth.
50. Analyzing SDO/HMI Data Using Python Contributed by Monica G. Bobra. Posted on April 24, 2016 The HMI team has developed several Python codes that can be used to conveniently analyze its many magnetic field data products. Check it out!
45. How is Nonlinear Force-Free Modeling Affected by the Spatial Resolution of the Boundary Data? Contributed by Marc DeRosa. Posted on October 26, 2015 The effect of the spatial resolution of the boundary data on nonlinear force-free extrapolations is systematically explored for a solar case.
