Pointing in the 2006 December run 
__________________________________________

  Pointing plots were made using currently available data 
in order to find any tendency.  
(We may have some more files in future.  Known problems 
are summarized in a separate text file "files_memo.txt" 
in the same directory.)  

 In these plots, M42.1, NGC253, Saturn, and Uranus data 
that contain a clear peak inside the SHARP field were 
used.  To get the pointing offsets, Larry's code "pointcorr" 
was used.  In total, 15 data points are included here.  
Note that, this time, only za dependency was investigated.  
Also, for Saturn data, za values were manually typed in 
to make the plots, because all za values were 90 for some 
reason (see attached file "files_memo.txt" for more detail).

 There was a strong dependency in za, as shown in the plots.  
When we subtract the effect with the fitting curves, 
the rms on az/za are  
1.22" and 1.75" in (cazo-fazo) and (czao-fzao) respectively. 

 Pointing corrected M42.1 image (m42p1_pocor.ps) is also 
attached here.
