What is the reason and method of data 'blackout'? When were the blackouts done? Are there other image areas, that may not be of interest, blacked out? When were those areas black out? What method was used?
Are there other image sources that show something there during the same time period?
I went to http://www.google.com/sky/ and did it myself, just yesterday. Do a search for Leo and then click on infrared, then move to the upper right corner and scroll over a bit, and you will see it. Then search for Virgo and do the same thing, in the lower left corner. Has to be on infrared.
Then I moved around a lot and found another, larger blackout - a large black section, but I forgot now where it was. I'm much more interested in the images that are partially blocked, because they obviously didn't black out the whole thing. The blackout itself might have a logical explanation, but what about the large object and it's smaller objects, and the object with the line going thru it? They stand out and are unmistakable.
I don't know the answers to your other questions. I just started researching this yesterday.
