The SURFACE EXPLORER allows you to visualize (hkl) indexed surfaces of commonly known single crystals using various options. The screen image can also be downloaded as a color PostScript file to be used for publication quality print output. Input is accepted by either filling in the form (upper part of the input page) or by providing explicit BALSAC file format input inside the file area (lower part of the input page, only for the experienced user).



"Input File (Balsac Format):" at the lower part of the input page 
starts the file input form. Here clicking "Balsac Format" gives the 
full definition of the BALSAC file format taken from the original 
BALSAC manual. 


The file input area (with scroll bars) accepts ASCII characters and
numbers according to the BALSAC file format by either keyboard or 
cut/paste input. 


Visualizing an incorrect input file shows a separate page starting 
with "FILE ERROR" which is followed by an area with the present file 
input text and an error message reading

  BALSAC FILE ERROR - reading Card N, (Line M) 

at the bottom where

  N refers to the sequence of input lines in the BALSAC file format 
    definition while 

  M denotes the line number in the file input area. 

The definition of the BALSAC file format can be obtained by clicking 
"Balsac Format" at the top of the page.


Click "VISUALIZE FILE" BUTTON to check the input given in the file area 
       for correctness and to start the visualization of the lattice 
       section on the OUTPUT PAGE:

            - generate PostScript picture file of the surface 
              (may be downloaded)

            - display screen image (GIF format) of the surface (optional)


Click "CLEAR FILE INPUT" BUTTON to clear all input inside the file 
       input area allowing you to start with input from scratch.


Click "PREVIOUS INPUT" BUTTON to replace the present input inside 
       the file input area by the text shown when the page was opened. 
       This allows you to return to your original file input after you 
       have made too many corrections.


Click "RETURN TO FORM"  to return to the original input page and to 
       start from scratch.


Click "HELP" to show the present help page.
