Where in the world are you getting TLE sets that don’t have a checksum? Boo!
It would be a one-line change to make NASAWASH always ignore the checksum on input (it always regenerates the checksum on output). With a little more effort this could be controlled by a command-line switch. I can probably generate a quick hack executable for you if needed. Let me know what platform. Or if you’re set up to compile C programs you shouldn’t have any trouble modifying NASAWASH. -Paul On Dec 21, 2013, at 6:05 AM, Jim White <[email protected]> wrote: > Thanks Paul.
