                    CALIBRATION FILE INFORMATION                              
                                                                              
     This directory contains supplemental data submitted to the P/G-Z archive 
by the Infrared Studies (IRSN) and Spectroscopy (SSN) Networks.               
                                                                              
     Two types of IR data are provided - Filter Tables and Images (non-       
comet).  The filter tables are referred to in some IRSN FITS headers as       
containing the filter information for specific observations (cf. the column   
FLTRTABL in the Table Data records of the observation files and the keyword   
DIS-CODE in the FITS headers of the Filter Tables).  The image data are       
intended to show detector response on various targets taken at times similar  
to the comet observations.                                                    
                                                                              
     For the Spectroscopy files, both 2-dimensional and 1-dimensional data are
provided for the sky and for laboratory comparison lines as reference         
"objects".  The data is usually unreduced but full documentation is provided  
in the FITS headers.                                                          
                                                                              
     The extensions for files of the calibration data, i.e., .TAB, .IMG, and  
.DAT, or for descriptive headers (.HDR and .LBL) follow the IHW filenaming    
conventions.  To reconstruct a genuine FITS (.FIT) file, the header and data  
files for the appropriate observation must be concatenated.                   
                                                                              
     The following table links the Infrared (non-comet) Images and the        
Spectroscopy Calibration files to the appropriate P/G-Z observation files:
