C7 Light Curve
You have discovered a Cepheid! Ferrarese et al. (1996) named
this Cepheid C7. Below is their plot of C7's light curve.
On Part I, Section B of your lab sheet, record the name of the
Cepheid, its grid section number (47), its average apparent V magnitude
(mv), and its period
(P). (Careful: the numbers decrease going up the vertical axis!)
When you're done, return to the main grid section
47 page to look for another Cepheid, or return to the main WF4 8x8 grid.
