This indicates to me that more was done to the image than could be accounted for by using this technique. Since this question has been raised, this is my response. If Mr. Hoagland can document, explain and demonstrate a legitimate means by which his image has been generated, I will gladly post his explanation and retract this article. It could be that the distortion of the data is an unintentional artifact of his processing and filtering technique. Imaging artifacts are not structures.
Human error is a distinct possibility.
Mr. Hoagland has posted a response. This page will stay. Somehow it seems that the name just fits the available data. At least, that's my theory.
