===============================================================================

This directory contains additional dust data files (n/k data).

You may send further data to swolf@astro.caltech.edu in order to add
them to this directory and thus making them available to the whole FEPS team.
The structure of these files is explained in detail in the DDS manual.


*******************************************************************************
WARNING:
* For several of these dust species the wavelength coverage is not sufficient
  (DDS internal criteria: 0.2-500 micron).
  In order to make these dust species 'available' for DDS, the n/k values
  have been extrapolated:

	(n,k)[0.2:lambda_min] = (n,k)[lambda_min]
	(n,k)[lambda_max:500] = (n,k)[lambda_max]
	
  {lambda_min/max are the minimum/maximum wavelength 
   for which n/k values are available}

  The resulting SEDs are therefore only of interest in respect of the location
  of spectral bands. The underlying continuum cannot be calculated correctly.

  See data files for details.
