Introduction to Using Hera for Imaging

The following is a dialog between a teacher and a student; read it and use it to answer the questions below.

    Teacher: "Well, my first question is, how many days of the week begin with the letter T?"

    Student: "Shucks, that one's easy. That'd be Today and Tomorrow."

    Teacher: (eyes opening wide) "That's not what I was thinking, but ... you do have a point though, and I guess I didn't specify, so I will give you credit for that answer."

    Teacher: "How about the next one?" "How many seconds in a year?"

    Student: "Now that one's harder," says the student, "but I've thought and thought about that and I guess the only answer can be twelve."

    Teacher: (astounded) "Twelve! Twelve! How in the world could you come up with twelve seconds in a year?"

    Student: "Aw, come on, there's gotta be twelve, January second, February second, March second... "

    Teacher: "I see where you're going with it. I guess I see your point, though that wasn't quite what I had in mind, but I'll give you credit for that one too."

Think about the following things to yourself:

  • Why do you think it is important for scientists to look at things from different perspectives?

  • What kinds of tools can scientists utilize to observe items from different perspectives?

During the activity that you will complete today, you will be utilizing the same tools that scientists do to look at their data in different ways.

Imagine the Universe is a service of the High Energy Astrophysics Science Archive Research Center (HEASARC), Dr. Alan Smale (Director), within the Astrophysics Science Division (ASD) at NASA's Goddard Space Flight Center.
