View your data
Use the [Choose file] button and then select the .csv file you used to calculate your magnitude and B-V colour (make sure the data is in the same columns as shown in the examples).
You will see a plot that shows the stars you measured:
- The x-coordinate is on the X-axis and y-coordinate is on the Y-axis.
- The colour of each circle represents the approximate colour of each star.
- The size of each circle represents the star's brightness with bigger circles meaning brighter.
