The format for your writeup should be that of an Astrophysical Journal paper. The following elements are necessary:
2. Abstract: a short paragraph summarizing the goals, results, and scientific implications of your project.
3. Introduction: ~ 2 pages giving the scientific context: what is it that you are studying, why is it scientifically important, what have other similar studies shown, and how your project will address the scientific questions.
4. Data and Analysis: ~ 3 pages describing the details of the imaging data and how you analysed the images.
5. Results: ~ 3 pages describing quantitative results of the data analysis. Specific things you should include here:
6. Discussion: ~ 3 pages discussing the implications of your results. In particular, what do the morphology, surface brightness profile, and color profile tell you about the stellar populations in M101 and the galaxy's evolution history. Think about things like the star forming history of the galaxy, the environment of the galaxy, how it compares to other spiral galaxies (either individual spiral galaxies or spiral galaxy populations in general).
- Your final B image of M101.
- Surface brightness profile for M101
- B-V color profile for M101
- Derived properties of M101's disk:
- exponential scale length (in arcminutes and in kiloparsecs),
- the approximate radius of the 25th mag/arcsec^2 isophote (called R25) in both arcmin and kpc,
- the disk central surface brightness (in B mag/arcsec^2, from your fit),
- the total brightness of the galaxy (in apparent and absolute V magnitude, and also in solar luminosities).
- Qualitative discussion of uncertainty (quantitative where possible, ie parameters of fits, etc)
- Comparison of your results to previously published measurements
7. References: A listing (ApJ style) of references you've cited in your paper. You should have ~ 12-15 references from scientific journals or monographs (not textbooks, educational websites, or popular magazines).
8. Appendix: attach a copy of any code you wrote for your analysis.
Notes and suggestions:
- Counting up the suggested page lengths for each section, your total paper should be about 10-12 single spaced pages, not including references or the code appendix. Figures in the body of the text are fine, but if you're making your figures really big so that you can fill pages and don't have to write as much, that will be obvious.
- You should cite ApJ style. That means that when you refer to someone else's work in your paper, you cite it in the text as "(Dewey et al 2010)" and then list it in the references as "Dewey, C., Cheatem, A., and Howe, J., ApJ, 454, 12 (2010)". In the reference list, that first number is the journal volume, and the second number is page number (for older papers) or paper number (for newer ones).
- Spelling, punctuation, and grammar all count. Spellcheck and proofread your paper! Revise as necessary.
