Some years ago a neighbor of mine, an amateur astronomer, invited me over to meet a couple of guests. He had invited one of them to make a presentation to his astronomy group on an alternative to RGB and it's advantages. I'm not sure which of them was making the presentation.

However, one of them was a NASA guy who was in charge of some of the resupply missions to ISS if they were American. If they were Russian he monitored them.

I asked him about the mission which had apparently had a Russian antenna in the way. He told me that was a Russian affair and he had been sent over there to monitor how they handled it. Apparently it was getting close to an abort and his boss in the US wanted to abort. He said he protested, reported that his boss trusted him and the Russian was handling it just as he would. At the last minute they got the proper software loaded and the antenna moved out of the way. He had other tidbits, but I don't remember them.

Although I don't have the slightest idea why he preferred another protocol for color imaging it was a fascinating evening. I was sorry to see it end.

And thanks for your post. I can begin to see how much information there is in those things and how it can be manipulated. I've often wondered.
