The document directory contains documentation files, where available, for the 
data set in this volume.  All document files will have an accompanying label  
file to describe content and structure.  Label files have the same name as the
main document file, with an extension of ".lbl".

        nir_log_20050628ut.asc [11 more files not listed] - "Observing Logs", 
        A log file for each night of the Comet 9P/Tempel 1 observing campaign,
        providing start and end times of each observation, exposure times,    
        filters, etc.  The last column of the log gives the spectrograph slit 
        being used (this slit will appear in the image).  If "Mirror" is      
        listed in the last column, no slit will be present.  For those series 
        of images where the target object (comet or flux star) was actively   
        being guided on the slit, the letter "G" will follow the slit name -  
        many of these data were taken simultaneously with spectra contained in
        the companion dataset "IRTF Near-IR Spectroscopy of Comet 9P-Tempel 1 
        V1.0".  Also included in these nightly logs are descriptions of the   
        sky conditions and a listing of optical depth (Tau at 225 GHz)        
        measurements as a function of time.  These Tau measurements (provided 
        by the Caltech Submillimeter Observatory) are strongly correlated with
        precipitable water vapor above Mauna Kea.
