HMI plans to provide vector field data in four categories: quick-look,
standard, on-demand and on-request. 

Basically, quick-look data products are mostly used for helping operating instruments and predicting space weather. Standard data products are served as monitor and reference to meet basic research needs. 

On-demand data products are completed for a small fraction of data when interesting things happen or whenever requested. It is expected that this kind of data products will serve most research purposes. 

On-request data products are completed when system resources allowed. The discussion is mainly focused on defining the four kinds of products.

Possible topics for discussion

 . 1. Quick-look data products: Which products are needed for these purposes? Whatresolution and cadence of data are needed?

 . 2. Requirements on the other three kinds of data products.

 . 3. Since changes of the horizontal field could occur in fairly short time-scale, any strategies to make synoptic maps of vector magnetic field physically meaningful?

 . 4. Plans for intercalibration of HMI line-of-sight fields with other instruments
