Creating a Limits File 

A limits file should be named like this: GEM00216.LIM (for run 216 on GEM), and should be in the same directory as your data files. Here is a simple example of a .LIM file...

(Note that the numbers given in this example are fictitious and should not be taken as recommendations.)

The first line gives the number of detector groups, ngroup. This should then be followed by a further ngroup lines, which should be arranged in order of increasing group number, with no omissions or duplications. Each line gives the group number, a flag, and the minimum and maximum Q-values to be used for calculating the merged result. The flag should be one or zero, indicating whether or not the group is to be included in the calculation of the merged result. The format of the file is free (the numbers must be separated, by spaces or a comma).

An example file g_f:template.lim is available and this file may be copied, renamed and modified.

A limits file can be generated automatically, for a given range of wavelength, by typing @g_f:makelim in GENIE or by typing run g_f:makelim outside GENIE.
