proposal
Based on work done with the JOP-39 data, Gurman, Thompson, myself,
and others recently submitted a paper to _Solar_Physics_ indicating
(among other things) that polar plumes have unipolar magnetic
footpoints[1]. Yi-Ming Wang recently contacted me about a paper
he has submitted to _Ap_J_Letters_[2] that comes to a conflicing
conclusion -- that polar plumes land on mixed-field regions.
Several EIT Co-Investigators (notably Thompson and Gurman) are
named as co-authors on *both* papers, putting them in the awkward
situation of endorsing both views. I propose to re-analyse the same
EIT data that Wang used, by comparing 171A stills to near-simultaneous
MDI magnetograms in a similar manner to the past analysis of the
JOP-39 data. This will elucidate whether the apparent conflict
is due to the particular data set, and whether the two teams
have a genuine disagreement -- or are merely talking "through"
each other.
