Good question! Atmospheric scientists aren't actually sure yet whether brown dwarfs should have "bands" like we see on Jupiter and other Solar system gas giants (this was discussed at a meeting in Washington, D.C. Jan 2014) -- and our mapping data wasn't quite sensitive enough to definitively answer that question. (We're less sensitive to axisymmetric features than we are to longitudinal variations). The vertical "stretching" of the map's features toward the poles is an unavoidable artifact of our analysis technique. Cloud patterns may be less elongated than they appear!

Moreover, the five-member Privacy and Civil Liberties Oversight Board said it’s been largely useless in thwarting terrorism.
“We have not identified a single instance involving a threat to the United States in which the program made a concrete difference in the outcome of a counterterrorism investigation,” the board wrote in the report released Thursday."

In some ways, the people pushing the Snowden-as-traitor narrative have a decided advantage here. This group comprises politicians, intelligence officials, lawmakers and others whose opinions carry the implicit power and weight of their offices. Whatever one thinks of Obama, Director of National Intelligence James Clapper and Alexander, they are among the more powerful men on earth and their public pronouncements by definition are important. If one of them declares Snowden to be a traitor or says that he should spend the rest of his life in prison for his actions, there is a sizable portion of the population who accepts that as fact.
That is not necessarily the case on the other side of the argument. However, many members of both the hero and traitor crowds formed their opinions reflexively, aligning themselves with the voices they support and then standing pat, regardless of the revelation of any new facts or evidence. They take the bits and pieces of Snowden’s story arc that fit with their own philosophy, use them to bolster their arguments and ignore the things that don’t help. This, of course, is in no way unique to the Snowden melodrama. It is a fact of life in today’s hyper-fragmented and hype-driven media environment, a climate in which strident opinions that fit on the CNN ticker or in a tweet have all but destroyed the possibility of nuanced discourse."
Hubble has better resolution at visible wavelengths, but remember we're seeing the planet's thermal radiation and not reflected (visible) light -- so the planet is over 10 times fainter in the visible than at at infrared wavelengths (Figure 6 in the paper). Hubble can also see into the infrared, but because it is smaller than the largest ground-based telescopes Hubble does not offer the best resolution in the infrared.
A 50% success rate means all their predictive tools are no better than flipping a coin; the only difference is their method has kept them employed.
Fairey and his lawyers have been arguing fair use — and that seems to be how the media and copyright watchdogs have been treating the dispute, but there's something more interesting, subtle, and insidious going on that no one has touched on. The Fairey poster is not just the photograph with some Photoshop effects applied to it — which would have certainly brought up all manner of fair use issues. It's been demonstrated that the poster image was traced from the photo (no doubt by hand), but that would actually make it an original creation, even when using something else as a jumping off point. Here's the catch: the photo was not a work of art carefully composed in a studio, it was taken at a public event where anyone standing in roughly the same spot could have taken the exact same shot.
Apparently, what the AP is arguing is that no one has the right to make a artistic representation of anything depicted in a photograph to which they hold the rights. This is not a threat to fair use. It's a threat to free speech, and the willful creation of a memory hole."
From Sen. Feinstein (D-CA): "Currently, S. 773 is awaiting action in the Committee on Commerce, Science, and Transportation and is currently undergoing some major revisions." If this information is still current, anyone concerned with this issue should contact the appropriate members of the committee.

What type of maps are these?
Many professional-style maps in the USA -- e.g. quad sheets, parcel/tract maps, etc. -- will have survey markers indicated. Ideally these would be set benchmark disks with longitude/latitude noted. Many maps also mark boundaries of townships, sections, and half- and quarter-sections, locations of which should be available from the local municipal authorities.
These sort of well-defined points are probably your best bet for empirical location, but if your maps are 100 years old the coordinates may not be precise enough for digital overlays. In the end, you may well be forced to manually align your maps with something more modern.
