; PURPOSE:  Records resolution where the Fourier shell correlation 
;    drops below threshold (0.5), and  corresponding
;    spatial frequency in a document file.   
;    Resolution = pixel size / spatial frequency
;
; I/O PARAMETERS AND FILES ARE SET HERE:
;
;   -------------- Input Registers (on command line) ---------------
;
; [freq]        Nyquist frequency                (Sent from caller)        
; [iter]        Iteration                        (Sent from caller)    
; [grp]         Group                            (Sent from caller)    
; [spfreq]      Interpolated spatial freq.       (Sent from caller)
