\fProcedure 2b: Using the information in your Light Curve on Figure 2, write down the information for the values in the box at the top of Figure 2: a. The Period = P is the time between peaks of the light curve. b. Use your calculator to find the Log of the period = Log P. c. Use your graph on Figure 1, and the Log P, to find the Absolute Magnitude = M. d. Average the highest and lowest apparent magnitude dots to find the average apparent magnitude = m. (Put your index finger on the highest magnitude dot and your thumb on the lowest magnitude dot and squeeze them together. Where they meet is the average apparent magnitude) e. Calculate the distance modulus = m - M. f. Use the distance modulus and Figure 3 to find the distance to the cluster Xi Perseus. Along the bottom of Figure 3, find your distance modulus (m-M). Go up from this point until you intersect the curved line, drawn on Figure 3. Go horizontally and read off the distance to the cluster.

Connect the dots, but do so in a smooth manner to best represent the variable pattern for the star. This type of graph is called a Light Curve. Table 3
