 ERROR 
 
 

ERROR string
Generates an error, and issue the string to the user. Permits to 
handle errors in command files.

 ESCALE 
 
 

The Entropy expression during Maximum Entropy run is computed as 
follow :
A = Escale * Sum(F(i))
P(i) = F(i)/A
S = -Sum( log(P(i)) * P(i) )

Escale should be set to 1.0 for normal operation

 EVALN 
 
 

EVALN x1 y1 {x2 y2}
evaluates the noise level as well as the overall offset of the data, 
over a area of the data. The results are stored in the NOISE and 
SHIFT contexts This command is called automatically whenever a data 
set is read. The command will prompt for the last selected region 
with the POINT command

see also : NOISE SHIFT

 
 evaln.g 
 
 

 evaln.g
 graphic interface for the evaln command.

 
 EXIT 
 
 

EXIT yes/no
Exit this program. You can choose to keep or to remove the log file
QUIT and BYE are also equivalent. As well as ^Z (F10) on VMS 
systems.
 

 
 EXPLIM 
 
 

This context holds the limit for the exponential function used in 
the Gull & Daniel algorithm, as well as in the GIFA algorithm.
A function exp2(x) is used which is
	- equal to exp(x)				if x <= explim
	- equal to exp(explim)*(x+1.0-explim)	if x >  explim
i.e. a linear extension of the exponential function is used fo x > 
explim.

 EXTRACT 
 
 

EXTRACT x1 y1 {x2 y2}
	Permits to extract a portion of the data currently displayed. 
Data can then be processed as a regular data-set. EXTRACT changes 
the value of OFFSET and SPECW accordingly. The command will prompt 
for the last selected region with the POINT command
