Magnetic field vector retrieval with the Helioseismic and Magnetic Imager
Listed in National Center for Atmospheric Research
We investigate the accuracy to which we can retrieve the solar photospheric magnetic field vector using the Helioseismic and Magnetic Imager (HMI) that will fly onboard of the Solar Dynamics Observatory by inverting simulated HMI profiles.
Description
The simulated profiles realistically take into account the effects of the photon noise, limited spectral resolution, instrumental polarization modulation, solar p modes, and temporal averaging.
The accuracy of the determination of the magnetic field vector is studied by considering the different operational modes of the instrument.
