ATM New Version of Figure

[Aplanatic@aol.com]

I have uploaded a new version of Figure, a DOS Foucault 
analysis program.

The URL is:

Version 4.5 has the following added features:

-- You can now enter the zone radii as either the 
inner and outer mask radii or as the effective center 
of the zone.

-- You can now enter up to four KE reading data sets 
in the KE Panel and have the program automatically 
average them.

-- In the Load Panel, the program automatically finds 
all data files with extension .fig and displays them for 
you. You can select one of these files using the cursors, 
or you can create a new file by highlighting the NEWFILE 
entry. The program then prompts you for a file name.

-- File Saves are now semi-automatic, the program will 
prompt you for a new file name or will verify an overwrite 
if information has been changed in the current file.

-- You can now see the effect of a central obstruction in 
the Diffraction Analysis Panel and the Spot Visualization 
Panel.

-- The Spot Visualization Panel now shows the diffraction 
pattern for an ideal mirror as well as for the actual mirror.

-- A new function has been added, Print. Pressing <F8> at 
any time causes the program to make a text file containing 
the measurement data, the mirror analysis, and the surface 
error profile. The Print File has the extension .res (for result).

Thanks to everyone that has made comments and suggestions
regarding improvements to the program.  And special thanks to 
Nils Olof and Jim Burrows who have reviewed and critiqued 
during the entire evolution of Figure.
