  On thursday, i worked on rearranging the list of images for Dr. Baum. She wants me to put them in order by what kind of filter and instrument was used. Then she wanted me to sum the exposure times and also include that in the list. This is taking me a while to do. I have learned how to alphabetize spreadsheets on excel and how to use the sum function. We had volleyball that afternoon and then i left a little early because I was leaving for ESG's that night.
