I decided to create a special thread for this topic. Previously information on IMG2PNG was scattered across various threads here.
I new version of IMG2PNG is now available. For those that don't know, this is a command line uitility that can convert various PDS formatted files to PNGs (8 or 16 bits per pixel depending on the input files). This utility should work for lots of different PDS files, e.g. MER, Pathfinder, Voyager, Galileo, Cassini, Stardust, various Mars orbiters, Mariner 9/10 (!), Viking Orbiter, Viking Lander, Magellan, Clementine, Messenger, New Horizons etc. The major new feature in the new version is the ability to convert FITS files. IMG2PNG can be downloaded by visiting http://www.mmedia.is/bjj/utils/img2png Any information on possible bugs welcome. |

Thanks everyone for the help. Works great now.
Emily, I realize cosmic ray hits wouldn't go away with calibration; I'm so used to my own deep-sky imaging where multiple sub exposures are combined to both increase the signal, as well as average out CR hits; same goes for my own planetary images taken with my camera and telescope. Not as used to putting planet images together with single exposures. I was hoping the faint "venetian blind" artifacts would be removed with calibration (horizontal bands that are barely above the background counts), but alas, it's not to be. |

I was hoping the faint "venetian blind" artifacts would be removed with calibration (horizontal bands that are barely above the background counts), but alas, it's not to be. Yeah, the 2Hz banding is hard to remove as it's not predictable. I don't think even the imaging team has a good solution to this. Basically involves advanced filtering of the image (helps if you have "black" areas around targets of interest) and is therefore not part of the standard calibration procedure. -------------------- |
