COMMENT This file contains a Fourier-domain noise PSD for the associated
COMMENT SPT-SZ temperature map for the 150 GHz frequency band
COMMENT and the ra5h30dec-55 field observed during the 2008 season.
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.
