-------
This is a book about the marvelous objects we can observe in the infrared, and the people who discovered them - not much technical detail about the instruments that make the measurements.  

The graphs are interesting, and tell us about instrument sensitivity:

 * p51 - Planetary nebula, λ 2 to 14 μm, 0 to 6e-16 W cm^2^μm.  Sharp peaks (chemical resonances?), many less than 0.1μm wide, 1e-16 to 4e-16 on top of a broad 10μm thermal(?) peak, 300K? p-p noise 2e-17  Fred Gillette at UCSD, The Two Micron Survey, terrestrial telescopes, 1967?

 * p57 - two graphs, PAH (Polycyclic Aromatic Hydrocarbon) peaks.  3 to 18 &mu;m <<BR>>NGC 2023: $S^0_v$ 0 to 2500e-31 W/Hz<<BR>>M17-SW: 0 to 8000e-31 W/Hz <<BR>>est 300e-31 p-p noise. Leger, Puget, Allamandola around 1985.

 * p111 - KOBE 2.7K black body background.  Presumably lots of averaging.

 * p175 - Herschel 190 to 315 &mu;m wavelength

 * Other graphs, only relative vertical units.

The book discusses these infrared observatories, extra information from wikipedia:
