COMMENT This file contains a Fourier-domain filter transfer function for the
COMMENT associated SPT-SZ temperature map for the 150 GHz frequency
COMMENT band and the ra5h30dec-55 field observed during the 2008 season. The
COMMENT transfer function was estimated by simulating and filtering observations
COMMENT of a map with a 0.75 arcmin FWHM Gaussian kernel centered at the
COMMENT location specified by the X_CEN/Y_CEN and RA_CEN/DEC_CEN keywords.
COMMENT Pixel numbers assume a zero-indexed array. The transfer function is for
COMMENT a subregion of the map covering approximately one-ninth of the map area.
COMMENT To avoid numerical artifacts, regions of the Fourier plane for which the
COMMENT Gaussian kernel amplitude was less than 1% were set to zero. The
COMMENT Fourier-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 sampling
COMMENT interval in that dimension.
COMMENT This file was produced for the first SPT data release.
