Number of spiral arms???

  • ragnartrains by ragnartrains

    How come the option "can't say" has disappeared from Classify regarding the number of spiral arms??? Often you can tell that you see a spiral but due to low resolution you can't give the number of arms. As it now is you have to guess to move forward...!

    It was intentional that the 'can't tell' option was removed, the Scientists will be able to learn more from a guess than if everyone selected the opt out option ๐Ÿ˜ƒ

    Agree with you. Yet, sometimes, that option is available. Yet again, if I see that option available and I select it (or not), as sometimes I'm not sure about how to classify something and I "restart", that option is ( or sometimes is not) available again. I can see it available once every 20-30 spiral galaxy. Is it random or has something to do with the image that we see?

    All depends on what survey you are classfying (e.g DECaLS, SDSS, UKIDSS etc.) - different surveys have different research goals, so the questions get changed accordingly!

    The restart option should always be available, I can't say I have noticed it disappearing. What browser are you using? or are you using the mobile app?

    Didn't new that there is an app as well. Can I get more info about app so I can have it on my phone also? ๐Ÿ˜„

    About restart, I wasn't talking about the restart button that disappear, but about the "can't tell" option available while classifying the arms of a galaxy (1, 2, ... can't tell). If I created some confusion, please excuse me, english is not my main language.

    As about the browser, I'm a big fan of Mozilla Firefox, which I currently use. If you suggest using Chrome for a better experience, I will give it a try.

    P.S.: Please provide more info about the App. Thank you.

    No Problem!

    You can find all the information regarding the App in this thread. I think the latest version of the Android app got released a few weeks ago, and is available for download on Google Play.

    I use both Firefox and Chrome - both are pretty good!
