Kevin Walsh                                                                   
                                                                              
                                                                              
All data reduction from different nights were done in a consistent            
manner. The BIAS frames from the entire night were median-combined to         
form a single Zero.fits image.                                                
                                                                              
Similarly the flat images were also combined for each filter, BVRI, to        
form a nightly flat in each filter flat_?.fits. The raw flats had the         
mean value of the bias strip subtracted, and then the Zero.fits image         
subtracted before they were median-combined and normalized to 1.0.            
                                                                              
From this point each raw object image was processed. The mean value of        
the each raw image bias strip was subtracted, followed by the                 
subtraction of the Zero.fits image. The flat image for the                    
cooresponding filter was then divided out.                                    
                                                                              
All image reduction was done in the IRAF package.                             
                                                                              
In the images, North is left and East is up.                                  
                                                                              
The overscan was not trimmed in the reduced files.                            
                                                                              
Very few bad columns exist in the data, but those that persist throughout     
the data set are columns 531, 547, and 980.
