Comparison of other missions to Spitzer

THIS PAGE IS INCOMPLETE AND DATED. your mileage may vary.

Spitzer's resolution is a strong function of wavelength. The following plot comes from the SOFIA website, and is from at least 2003 if not earlier.

Spitzer's sensitivity, also from the SOFIA website, and is also from at least 2003 if not earlier.

This plot is from WISE. WISE is an all-sky survey mission that operates at 3.4, 4.6, 12, and 22 microns. It is lower resolution and lower sensitivity than Spitzer, but it is all-sky (whereas Spitzer is a pointed observatory). This plot compares several different large surveys. Spitzer does not appear because it is not a survey mission.
