Unzipping SPICA_READ1A.ZIP will create a subdirectory, SPICA_READ1A.          
The main procedure for reading level 1A SPICAV or SPICAM data is              
SPICA_Read_1A.pro                                                             
                                                                              
After entering IDL, compile and run the routine. This routine use the astron  
and fits librairies of IDL. You can also find them in the /lib subdirectory.

For example, if you select the file "SPIV_1AU_0023A01_N_01.FIT" in the DATA   
directory of this package,the following message will be displayed:

The file SPIV_1AU_0023A01_N_01.FIT was read succesfully!                      
                                                                              
You now have read the FIT file, and you can access to the data and information
