[PARAMETERS]
bool    | band | =n |  [y/n] | 	if y, compute instantaneous bandwidth 
bool    | complex | =n |  [y/n] | 	if y, use complex-valued computations 
bool    | hertz | =n |  [y/n] | 	if y, convert output to Hertz 
int     | niter | =100 |   | 	number of iterations 
int     | order | =100 |   | 	Hilbert transformer order 
int     | rect# | =(1,1,...) |   | 	smoothing radius on #-th axis 
float   | ref | =1. |   | 	Hilbert transformer reference (0.5 < ref <= 1) 
bool    | verb | =n |  [y/n] | 	verbosity
