COMMENT FITS (Flexible Image Transport System) format is defined in 'Astronomy  
COMMENT and Astrophysics', volume 376, page 359; bibcode 2001A&A...376..359H    
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.
