COMMENT This PSD is for a subregion of the map covering approximately COMMENT one-ninth of the map area. The center of the mask used for COMMENT defining the subregion is indicated in the X_CEN/Y_CEN and COMMENT RA_CEN/DEC_CEN keywords. Pixel numbers assume a zero-indexed COMMENT array. The units of this PSD are K and not K^2. The Fourier- COMMENT domain grid in each dimension corresponds to 0, 2pi/(NT), COMMENT 2*2pi/(NT), ..., (N/2-1)*2pi/(NT), 2pi/(2T),-(N/2-1)*2pi/(NT), COMMENT ..., -2pi/(NT) where N is the number of elements and T is the COMMENT sampling interval in that dimension. COMMENT This file was produced for the first SPT data release.
