------------------------------------------------------------------------------- David Schlegel, Durham, 26 Jan 1998 ------------------------------------------------------------------------------- Extinction in Different Bandpasses ---------------------------------- Assuming an R_V=3.1 extinction curve, the dust maps should be multiplied by the value in the final column to determine the extinction in a given passband. The standard optical-IR bandpasses are represented by the CTIO and UKIRT transmission curves. For further details, see Appendix B of the text.
