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

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