WMAP + SDSS

What is this?

The colored sphere is Cosmic Microwave Background as mapped by the NASA/WMAP Science Team. The points are 250 000 galaxies and 35 000 quasars found by the Sloan Digital Sky Survey. (Science Magazine called these two projects together the biggest science story of 2003.)

How do I run this?

Windows: Click on wmapsdss.bat to run on a regular computer, on wmapsdss_geowall.bat to run on a GeoWall.

Linux To run on a regular computer, go to the directory where this README.html file is, and type

   chmod +x wmapsdss.csh
   ./wmapsdss.csh

To run on a GeoWall, do the same with wmapsdss_geowall.csh

Who put this together?

Mark Subbarao (subbarao@oddjob.uchicago.edu). Mark is a researcher in the Dept of Astronomy & Astrophysics at the University of Chicago, and astronomer at Adler Planetarium.

Dinoj Surendran (dinoj@cs.uchicago.edu) is a doctoral candidate in the Computer Science Department, University of Chicago. He was an intern in the SCOPE 2003-4 Museum Presentations of Science Program when he and Mark worked on this project.

Who can use it?

You. For free. But please give us and the science sources some credit!

For the formalities about credits for official stuff, contact Randy Landsberg (randy@oddjob.uchicago.edu), Director of Outreach at the Kavli Institute of Cosmological Physics, and Department of Astronomy and Astrophysics at the University of Chicago. Mark and Dinoj work/ed with him on this and several other projects.

How do I navigate?

The key is to press a mouse button down, move the mouse, and release the mouse button. Navigation is inertia-based, so whatever you were doing when the mouse button is released continue to happens. If you want to stop movement, click once, without moving your mouse during the click.

Rotation : left click & hold.
Zooming: Right click (and hold!) the mouse and move up and down. (If you have a Mac with a one-button mouse, press the option key as you click that button.)
Stopping motion: click once with the mouse.

To quit, press escape.

What software is this running on?

Partiview, by Stuart Levy et al. Stuart is a research programmer at the Experimental Technologies Division of the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign.
