An important point of any program dealing with data reduction is
the ability to visualize or print data in a fast and reliable way. For
this purpose a short introduction to the plotting capabilities of Frida-1
is given below.
A figure shown in the Textronix window can be printed by typing
'gp <file-name.ps>' at the command line. If <file-name.ps> is
omitted a file 'l#.ps' with '#' being the smallest not yet existing
number is created. The ps-file contains the file g2.ps, axis
definitions and the data provided by Frida-1. The created figure can
be readily opened with a PostScript viewer.
For creating a file containing multiple figures at once, the new
command gs has been implemented. Using this command instead
of gp creates the postscript file without the 'wups05a.ps' header
defining the different non-Standard PostScript commands used
in the file. This makes it easier to concatenate a number of PostScript
files created in this way to a single file. To print or visualize files
created with gs the header 'wups05a.ps' has to be attached by
e. g. 'cat wups05a.ps file.ps > ~/P.ps'. The latter may be defined
as alias 'gn' in your '.bashrc'.
In the file 'g3.ps' as well as at the bottom of 'g2.ps' there are a
number of switches that allow to modify the ps-file. A figure containing
a number of different possibilities like Greek letters, annotations,
lists for curve descriptions can be obtained upon request from Florian
