Description

This is a temporary work-up of this target. I encountered, for the first time, the problem of correlated noise or “walking noise”. At the time I took this image I hadn’t added dithering to my imaging repertoire yet (which would have avoided the walking noise problem). I guess they say “dither or die” for a reason! I did some processing gymnastics in Photoshop to minimize this noise but you can still see some of it. My plan is to take an equal number of additional subs while dithering each one and add those to the 5/31 session. That will give me 8 hours of data with the equivalent of having dithered every other sub. Hopefully, that will eliminate the walking noise.
