I am trying to learn the correct identification of craters. After completing my markup of a crowded crater image with my green rings, I got a pop-up msg to the effect of '56% score, 9 correct, 7 missed and 20 false positives - here are the correct identifications marked over yours'. The moon image now showed with 16 yellow rings. While not concerned with the score so far as for my standings, I do see it as a direct measure of my individual accuracy rating. I really do want to improve for the benefit of the project. However, not having committed all 36 of my marked locations to memory, showing just 16 yellow rings now does not help me much to determine which were the ones I missed, incorrectly marked or what the differences are between the correct marked craters and the ones I previously marked incorrectly. Since my green marks are not displayed on this corrected image and I cannot use the back function to retrieve my markups, I cannot find any way to compare my markup effort to the correct marks.
So is my monitor set wrong so something on the image is not displaying? Should I be seeing more than just the original moon image and 16 'correct' yellow ring marked craters?
For my next attempt, I got stricter on my ID's and scored (I think) 33% - with 9 correct, 0 false positive and 16 missed. The corrected screen showed 25 yellow rings but still no way to determine which were the ones where I had been correct.
