CONCLUSION.

POLYNOMIAL 


	
only good for slowly varying baselines. 

	
Fast.


LINEAR PREDICTION 


	
works well only for simple baselines. 

	
very slow for complex spectra.


MEDIAN EXTREMA 


	
fast and general. 

	
occasional peak distortion.

	
problems at edges of spectra or when baseline
 
	  information is limited.


MAXIMUM ENTROPY INITIAL POINT 


	
works well if distortion is in early point of fid. 

	
independent of spectrum complexity.


MAXIMUM ENTROPY SIMULATION 


	
the most flexible and reliable method. 

	
but slower than polynomial and median methods. 

	
gives additional information i.e. deconvolution.
