  • IRAC Color-Color diagrams showing the locations of prominent classes of astronomical objects in 2-color space [ gif ] [ ps ]

  • Composite near-infrared intensity observed by the Diffuse Infrared Background Experiment (DIRBE) instrument on the Cosmic Background Explorer (COBE) in the 1.25, 2.2, and 3.5 micron wavelength bands. The images are encoded in the blue, green, and red color ranges, respectively. (credit Hauser, M. G., Kelsall, T., Leisawitz, D., & Weiland, J. 1995, COBE Diffuse Infrared Background Experiment Explanatory Supplement, Version 2.0, COBE Ref. Pub. No. 95-A (Greenbelt, MD: NASA/GSFC) ) [ gif ] [ ps ]

  • Large 4x5 foot poster of the GLIMPSE survey region based on MSX 8 micron data [ gzipped ps ]

  • Histogram of number of saturated point sources as a function of galactic longitude based on MSX 8 micron point source catalog. (Figure produced by Bob Benjamin) data [ gif ]

[IMAGE - ]
  • Another histogram just showing saturation at inner longitudes, with source counts extrapolated to fainter magnitudes. This figure is a good argument for doing 2 sec rather than 12 sec exposures. With 2 sec exposures, only 2-3 sources will saturate per IRAC field, even in the inner parts of the Plane. data [ gif ]
