As long as some notation of the issue is available in this forum, that
should help a number of users wanting to work with it for now.
Is there any protocol for others updating the Wiki entry? I've just
joined Scipy but been a member of AstroPy since its inception - but I
have yet to write or update a Wiki page.
I'm still getting some type of 'shifting' of my dataset after running
LIC, so I need to examine the Cabral reference more closely. I think
I'm still missing something.
