Hi,
I’m regular follower of NH and I’m also interested in the 2nd leg of the mission, i.e the 2016+ KBOs encounters. Does anyone know when operations about this leg (starting with searching objects of interest with HST or some other earth-based means, I suppose) are expected to begin ? |

John,
Good to know, I wasn't implying you're doing byte math, just trying to give a simple example. I understand now about using -/+ math and stretching it to make gray the middle. I think this is an example of the horizontal banding tfisher referred to. It's not perfectly horizontal, but displaces downwards a few pixels across the whole image. Here's something interesting. Assuming these two asteroids are at the same distance (I'm using 2.5 AU, center of the belt ), they're only ~ 20,000 km apart. -------------------- Space Enthusiast Richard Hendricks

Yes, that matches what I have been seeing. Thinking a bit more, I bet it starts out completely horizontal as the image comes from the ccd. But to subtract two images, they first have to be reprojected to a common frame of reference, so it isn't quite horizontal anymore. |
