This file described how to use the DICal_Gui routine to perform custom        
calibrations.

1. RUNNING DICAL_GUI                                                          
------------------------------                                                
To run DICal_Gui, you must first be in an IDL session in IDL 5.4 or greater.  
Then, simply run the DICal_Gui routine.

Options, Text Viewer and Image Preview Windows.

3. PERFORMING A CALIBRATION                                                   
------------------------------                                                
This section outlines the process needed to perform a custom calibration.     
                                                                              
3.1 OPENING A FILE                                                            
------------------------------                                                
There are two modes for the calibration, single and batch.                    
                                                                              
To calibrate a single image, simply click File->Open from the menu bar        
and select the .fit file to calibrate.                                        
                                                                              
To calibrate a batch of images, once again, just click File->Open from the    
menu bar, only this time select a text file containing a list of files to     
calibrate. These files must be specified one per line and must be relative    
to the current directory.
