Get out of RGZoo! (i.e. go beyond)

  • DocR by DocR scientist

    Thanks to everyone who has been exploring other surveys to help figure out what's going on with RGZoo objects. We've responded to some of your suggestions, and there are now a variety of links available below the image when you discuss an object (FIRST, NVSS, SDSS and WISE). And there's more you can do!

    FIRST and NVSS now give you matched 9 arcminute fields (0.15deg), 3 times the size of the RGZ field. If you take those queries, you can also modify them to do other things pretty easily. So for example, here's the result from clicking the NVSS button on ARG00002zkc and then copying the url:
    http://skyview.gsfc.nasa.gov/cgi-bin/images?Survey=nvss&position=175.724,11.024&Pixels=300&Size=0.15&Return=GIF
    You can change the size of the field you're seeing 0.15 to 0.3, for example, but if you do that, you should also increase the number of pixels. You can change the name of the survey, so if you'd like to use the same query for FIRST, just change nvss to first.

    For the adventurous, and if you have the software available to view FITS images, you can change Return=FITS, save the file, and open it in your FITS viewer. Saving multiple images in FITS lets you do all kinds of cool stuff.

    SDSS button now takes you to Data Release 10 - the latest, although we are still ironing out some little bugs.

    Please post your own suggestions here for other participants. Thanks again and ad astra !

    And we'll put up a blog post shortly discussing the difference between all the surveys you can see. As an addition - this is the first ever project we've done using data at very different wavelengths, and it's a BIG conceptual leap to make. The team has been really impressed with the level of interest and discussion for the subjects so far, and hope it'll continue. Thanks again!
