Somewhat less coherent (or less standalone) materials

Finding the diameter of a region we care about -- Dr. Luisa Rebull, 2018, for the Ceph-C team

to do:

• measuring angular size of objects, e.g., cartwheel galaxy, in several different wavelengths. is it the same in different wavelengths?
• distances between clumps in ic417 and relationship to ages of stars
