These files were created in DS9 in an RGB frame with MIPS24 in blue, IRAC4 in green, and IRAC1 in blue.  No scientific method was used to create these images besides setting the scaling to log for every frame (and this was done because artifacts appear in the fainter galaxies when using other scaling which make the images less "pretty").  Once the color channels were loaded the contrast and bias were adjusted channel by channel until the contrast was maximized and the noise minimized.  After this the images were adjusted until I (Shawn) felt they looked nice.  Feel free to use your own methods if you don't think an image is pretty enough!
