TA Lecture Notes Outline

The following lecture notes only gives you idea how to use tools for data reduction. You must be aware of what you are doing! Identical procedure to the lecture note may give different results, depending on what you've done other than what I did when I make the notes.

Preface in English and Korean (Korean version is not being updated for months: please see the Eng version)

1. Installation and LINUX Basic

2. Python Basic

3. Get the Taste (showing few examples using HST data)

4. Reducing Ground-Based Observation Data: Concepts

5. How to IRAF (see appendix D)

6. Simple Preprocessing Using Python

7. Cosmic-Ray Rejection

8. photutils (1): Star Finding

9. photutils (2): SExtractor Sky

10. photutils (3): Annulus Sky

11. photutils (4): Aperture Photometry

12. photutils (5): Extended Sources and Morphology, Sersic Profile
