OBJECT = 'ALL-SKY ' / Portion of sky given
COMMENT This file contains the spatial dust template used in the 3-year and
COMMENT 5-year WMAP template foreground fitting and removal process.
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.
