My Doctoral Thesis

Here is a link to my PAPER thesis for posterity.  It included a catalog, as well as studies of calibration stability and noise properties. I included a lot of extra information about the 32 antenna catalog that was cut from the original letter.  Then, looking at 12 nights of data I found that despite high
