Infrared Fluxes

Spectral Energy Distributions

This SED was created using the sensitivity and saturation values available in November 2004. The black dots are the object surface brightness calculated by assuming the fluxes listed above are uniformly distributed throughout the beam sizes quoted in the reference papers. The green and red lines are the respective sensitivity and saturation limits for each instrument. The sensitivity values used are for a 5 sigma detection of an extended source with a 500 second exposure.
