I know it may be too early for such a thread, but an announcement has to be made.
The official website of the LROC camera is: http://lroc.sese.asu.edu/ A brief description plus status is available here: http://www.msss.com/lro/lroc/index.html |

Is it just me, or - when loading the TIF's at full res, there appears to be some sort of interlacing (vertically). i.e. one column of pixels is bright, the next dark..bright, dark etc etc.
Attached zoom from http://wms.lroc.asu.edu/lroc_browse/view/nacl00000145 I guess some sort of adaptive amplification to create a pseudo enhanced dynamic range might be involved....or it might be a processing error, or it might be just something to do with the TIF's. You can sort of back it out with some VERY rudimentary Photoshopping (doesn't quite get the shadows...someone cleverer than I could do it). I'd expect proper calibration (which is, after all, the point of these early images) would eliminate it. I found a different chunt and had a go at it |

Definitely looks like something a flatfield (or possibly a dark model) would fix so I wouldn't worry about it much. Reminds me a bit of the awful dark current noise in VIMS visual channel.
