HMI Magnetic Field Products

Line-of-sight magnetic field will be computed from Doppler Velocity in two polarizations, as is done for MDI.

Vector Field will be computed from Stokes parameters derived from an independent set of polarized filtergrams.

After launch the possibility of combining the two cameras will be explored.

The basic line-of-sight cadence is 45 seconds. The basic vector field cadence in 90 seconds.

Vector field data products will be the following quantities and uncertainties on each

• |B| - total flux
• Filling factor
• Inclination (gamma) to the line of sight
• Azimuth (phi) relative to solar north
• Magnetic line-of sight velocity

Data will be exported in a variety of coordinate systems: Bx,By,Bz, B_r,gamma,phi, and Br,Btheta,Bphi
