Thanks very much for making these textures available John.
As always, much appreciated by the Brain-Dead.

Hey friends,

I must say that I find it highly unfair and bad style that the new Pluto/Charon textures by Marc Buie and collaborators are offered here without any reference to the texture origin/ original rersearch papers! The work that led to these textures took six years of running many computers in parallel as well a lots of original research.

At shatters net this seems to be worh: NOTHING, not even a proper reference.

"PLUTO AND CHARON WITH THE HUBBLE SPACE TELESCOPE. II. RESOLVING CHANGES ON PLUTO’S
SURFACE AND A MAP FOR CHARON

i was not planning on getting into a discussion - when Google is there for those interested to do some basic research
that is one reason i did not add to this thread
http://forum.celestialmatters.org/viewtopic.php?t=362

But you did not add a link to my respective CM thread either.

When displaying proprietary images, links to the places of origin are often required for legal purposes (NASA, ESA,...). Giving credits to original research and the authors involved serves also as an acknowledgement for their work!. This is only fair and should not depend on peoples' Googling skills..

Marc Buie wrote to me explicitly that he expects clearcut credit for the use of his textures. Using any contents from the Astronomical Journal (see above) is NON-trivial (as Marc wrote) and requires written consent. The colored AJ images are definitely NOT in the public domain. Also none of the resources you quoted in the README above contains 2k colored textures for download as far as I can tell.

The only downloadable, colored 1800x900 Pluto/Charon textures that Marc B. pointed me to are from his (dedicated) WEB site, the link to which one also finds in my preceding CM thread about the new Pluto/Charon imaging by Marc Buie and collaborators...

the old 1994 map as blue

then recolored this
using the new colors as mentioned in the pdf

from the 720x360 images i ran GRAYCstoration and resynthesizer
on them to bump up to 2048x1024 for pluto
to get this ( offset 90 deg)

Yeah, that's good. I was somehow suspecting you did it that way, since I was really looking around to locate a downloadable colored texture of ~2k size. The only one I found was from Marc Buie's site, but it had this synthesized surface structuring in addition...

Thanks! Just a question: does the Pluto's texture within the pack above supersede that already hosted on ML? Is more accurate or...

ps
once installed the celestia default "alt texture" is still there on the r-click menu , i did not remove this .

No problem. I'd already remove that with your previous texture.
