raw data looks like. In the next section we'll use {\tt imexam} to see  how your data changes through the reduction process.  At this point it is worthwhile considering exactly what you are looking at. When an image is displayed, some stars appear to have a larger diameter than others. What is going on? Is the size of the image of each star different?\footnote{Each different?  %\footnote{Each  pixel on this CCD has an angular size of approximately 1/2 arcsecond. Assuming these stars are the same size as the Sun and 1104 pc away, what is their angular size? So what is causing their images to be larger than this on the CCD?} Each pixel on this CCD has an angular size of approximately 1/2 arcsecond. Assuming these stars are the same size as the Sun and 1104 pc away, what is their angular size? So what is causing their images to be larger than this on the CCD?  You can move the cursor over the display window and the count value for pixels will be displayed. Is there are difference between ``large'' stars and ``small'' stars? Make some radial profile plots of different stars. What do you notice? Is the radius over which light is spread for a ``large'' star actually any different than for a ``small'' star? \subsubsection{Processing the Data}
