1. The Helioseismic & Magnetic Imager – Magnetic Investigations HMI Data Processing HINODE Spectropolarimetric Magnetic Field Inverted with HMI-like Algorithm by S. Tomczyk & J.

Teams are forming to address the principle scientific goals of the mission. These topics, outlined in the HMI Science Plan (http://hmi.stanford.edu/doc/Science_Plan/HMI_Science_Plan.pdf) encompass a broad range of science that will be enabled by HMI magnetic field observations. The Co-I team desperately needs your participation to take full advantage of the opportunities provided. Polarized filtergrams around the Fe I spectral line at 617.3 nm made with the HMI tunable narrow band filter enable determination of all three components of the vector photospheric magnetic field in half arc second pixels with a cadence of five minutes at all times. Development of pipeline processing modules to produce the full menu of data products is currently underway. The final data products are presently being defined. Some STANDARD products will be computed at all times, others will be produced On DEMAND or during times of special interest. Some data products requiring intensive processing will only be produced On REQUEST when resources allow.
