Cathartic

Weird I know. I like the idea that I’m helping these scientists. Looking at 3 static images over and over also helps my mind not race. I have no idea if I’ll ever get feedback on if I correctly identified a black hole but it’s not a big deal for me. You guys are busy unlocking the secrets of the universe and this app probably isn’t top priority XD Anyway! Thanks for letting me be a part of this

Love These Citizen Science Things

Nemo ... has some excellent points. I just fired the app up this evening and it says there's nothing to analyze right now. Are we still engaged, or is my analyzing so bad that they don't want my help anymore? Anyway, hope there's more work in the future.

Needs Feedback

This app is a good idea: enlist people to help find kilanova in sky surveys by excluding non-astrophysical light sources. They train you with samples, BUT there is no feedback when you assess transients, and no sense what proportion are likely to be ‘real’. I think when you mark ‘real’, you are just saying, ‘yeah, this is an astrophysical light-source,’ not ‘this is a kilanova.’ That would mean the ratio of real to bogus is much higher. But the app doesn’t make that very clear, so I select unknown quite a bit. What would b great would be a quiz against a vetted set of transients. That way you could guess then see the correct answer. New quizzes every so often between actual assessments would be great. I don’t want to me incorrectly training the algorithm!! Also, does the app need a certain number of ‘real’ selections on a given sample to be added to the real set, or is it just my assessment? Yikes! I love the idea of supporting the effort; it feels meaningful. But a community, message board, quizzes, etc would go a long way in making me feel I am doing more good than harm.
