Purpose

   Defines values and attributes of peak areas.

Example

   FAREA 3 / sum(4) g(10000) r

   fixes the sum of the areas of peaks number 3 and 4 to 10000.
  Peak number 4 is the reference peak (not changed)

   FAREA 3 / sum(4) g(10000)

   The area of peak number 3 is set to 10000.
   The sum of the areas of peaks number 3 and 4 is fixed at the value
   10000 + the area of peak number 4.
 

List of peak numbers. peaks=* means all peaks.
   

List of guess values for peak areas.
If only a single value is given it is assigned to all specified peaks.

List of lower limits for peak areas.
Must not exceed the current values of peak areas.
Further conventions see command parameter GUESS().

List of upper limits for peak areas.
Must not be exceeded by the current values of peak areas.
Further conventions see command parameter GUESS().

The specified peak areas are relatively fixed.
The differences, sums or quotients, respectively,
of the specified peaks and the reference peak pref
are held constant during iterations.

The specified peak areas are held constant during iterations

The specified peak areas are allowed to vary during iterations

For relatively fixed peak areas (DIFF() SUM()QUOT())
the guess values (GUESS()) are assumed
to be difference, sum or quotient with respect to the corresponding
reference peak parameters.

Limits of the specified areas are set to infinity

List the specified peak areas
