COMMENT The dust template was generated by smoothing the 94 GHz all-sky COMMENT 2-component model (model 8) prediction of Finkbeiner, Davis and COMMENT Schlegel (1999) with a Gaussian kernel to a FWHM of 1 degree. COMMENT This file is distributed and maintained by LAMBDA. An unsmoothed COMMENT version of the 94 GHz dust model map is also available from LAMBDA.
