There are 62 stars to measure in that catalog.

Make all the measurements and when your ready to publish them to global view. Do so. That way your actual HR diagram will get submitted.

Now answer the following questions:

1. Which stars (star names are given in the drop down list associated with the catalog) are most like the Sun.

2. Which star is likely a Red Giant?

3. Which star is the hottest and which star is the coolest?

4. Which star or stars are no longer on the main sequence?

5. Is this sample a representative sample? If so why?, If not why not?
