Hi there, congratulations scientist (and everybody here! 😃) to first data release. So... what now? Is this over? Can we flag more objects, or project is over? Well... what is now the priority? Deep space objects? Dark nebulaes? Red fuzzy objects? Still bubbles?

We will continue to flag stuff and whatever the science team finds interesting (through our going "hey that looks interesting!") will be looked at. So no the project it in no way over.

No the project is definitely not over! While analysing the data from the past year, we learnt a lot about what we need to do better, so we're planning to add some new tasks to help us interpret the data more accurately, and also improve our own processing algorithm. In time this will result in a 2nd data release of bubbles. In the mean time we're still working on processing the classifications of "other objects" - red fuzzies, green knots etc. We will also add new data from an extension to the original surveys with Spitzer - the images are being readied for that at the moment. Thanks for all your classifications, we're really pleased with the results so far, and beyond us in the project team the astronomy community is excited about these new catalogues as well.

I am reading it and I am trying to understand it. μm is micrometers right? For the equation on page six it is the square root of the two mixed fractions that have variance for the coordinate value and each of those has the zoom size as the numerator and the "B and the l" are the coordinates of the galactic scale as the denominator right?

@Fezman92 - the equation for dispersion on p. 6 doesn't contain fractions. The lower letters are just subscripts: sigma_l and sigma_b. b is the galactic latitude coordinate, l is the galactic longitude. The sigma value for each of these is the variance on the classifications we received from the users for that particular bubble - different users will place the bubble centre at slightly different positions, and the dispersion we defined places a number on that. We don't need to take the zoom size of the images into consideration for this particular calculation, only when we talk about sizes does that come into play.
If the dispersion is small we can argue that everyone agreed very well on the position of that particular bubble. A high dispersion means that the drawings were more spread out around the centre, and that perhaps there are multiple bubbles there or the bubble is very faint or fuzzy. Does that make sense?
And yes, µm is micrometers.

Yes that does. Thanks for clarification. 😃
