Disk Detective Talk

Can someone tell me what this is... I know it's nothing 'special', I just want to know what's going on.

    Why is it squashed in the WISE1 frame?

    Hi Akim

    This is what is going on:

    There is an issue in the AllWISE data concerning saturation and dropouts at WISE 1 -2, i've seen a lot of dropout flagging since this post, but when you spot one you should check for the AllSky data for the IR excess, here:

    #dropout #AllSky excess 0.034

    sometimes you have a dropout AND a genuine IR excess.

    sometimes you have a W2 dropout too:
