Modify Concept: (various solar regions)

[danseaton]

Name the concept in question
Solar K coronal region
http://astrothesaurus.org/uat/2042
Solar F coronal region
http://astrothesaurus.org/uat/1991
Solar E coronal region
http://astrothesaurus.org/uat/1990
Solar M coronal region
http://astrothesaurus.org/uat/984

Describe the change
The K, F, and E coronae are not regions, they are all different observational manifestations of the corona — they all refer to the same region, and the difference is the physical process by which generate the observations signatures we detect. These should be renamed as "Solar E corona", "Solar F corona", "Solar K corona".

I do not know what the M corona is supposed to be referring to. It is not in general use, and I recommend deprecating this keyword.

Please include any additional comments/feedback

K, F, and E corona will be updated as recommended above.

The M corona concept has its origins in the IAU thesuarus (http://www.mso.anu.edu.au/library/thesaurus/english/MREGIONS.html) and the IVOA Thesaurus (http://www.ivoa.net/rdf/Vocabularies/vocabularies-20091007/IVOAT/dict/M.html#mRegion).
Will need to look into this further.

"....the solar M-regions should be identified with the central portion of magnetically open solar regions, or coronal holes."

Gulbrandsen, A. The solar M-region problem - An old problem now facing its solution? Planetary and Space Science, Volume 23, Issue 1, p. 143-149.

It looks like "solar m regions" are something we now identify as "coronal holes".
@danseaton does this seem likely to you?

[danseaton]

Agreed, this sounds right to me. I would probably deprecate this keyword in favor of the much more widely used term coronal hole.

Leon Golub (AAS Solar editor) also concurs.

Suggestions accepted and implemented, will be included in the upcoming release.
