Today's my birthday! yay. we had doughnuts during our meeting this morning. I copied numbers into excel today which was a pain because there were about 30 new objects and each with about 30 values to plug in. It took a long time to finish the whole spreadsheet, but I finally finished it. I also subtracted the oxygen and sulfur to get more iron lines from more objects using IDL. with the program, it turned out to be much faster to subtract the arrays.
