Table 8.5: Average normalized ultraviolet extinction as a function of wavelength.

The table above lists extinction from interstellar reddening at ultraviolet wavelengths. These values have been derived to apply to our Galaxy, and the reddening laws for extragalactic objects can be very different. More information on the effects of reddening may be found in the bibliography in Chapter 9. The above values are from Code et al. (1976). Seaton (1979) has provided convenient fits to ultraviolet extinction for x = 1/l, with l in microns:
