| Jul 4 at 16:08 | comment | added | Ritvik Sai Narayan | Here are the papers I referenced: A Hubble Space Telescope transit light curve for GJ 436b DOI: 10.1051/0004-6361:200810013 HST/FGS Photometry of Planetary Transits of HD 209458 DOI: 10.1063/1.1774516 Perhaps, this is my own lack of knowledge, but I seem to have trouble in how to use IRAF for the data reduction/light curve fitting pipeline. I have RAW fits files from the FGS. Questions I have: - How can I find my star in the image based on RA and Dec? (I have some knowledge on how to do this using python via Astropy's WCS) - How can I calcuate photometry values for a light curve? | |

What information are you missing, where exactly do you get stuck? Please be specific. What is wrong with the IRAF software? It's readily available and well-documented, its latest release from April this year. The more you elaborate, the more helpful any answer can be. | |
