Abstract: NASA's Cosmic Background Explorer (COBE) Differential Microwave Radiometers (DMR) mapped the anisotropy of the Cosmic Micro\-wave Background. The instrument is sensitive to linear polarization. The extraction of polarization information, however, is challenging, both algorithmically and computationally. Specifically, the model functions used must be defined with care, and the issue of degrees of freedom in the map that are not determined by the differential DMR data must be addressed. Managing the size of the calculation is also important. The National Aeronautics and Space Administration/Goddard Space Flight Center (NASA/GSFC) is responsible for the design, development, and operation of the Cosmic Background Explorer (COBE). Scientific guidance is provided by the COBE Science Working Group. GSFC is also responsible for the development of the analysis software and for the production of the mission data sets.
