Programação
-
In this section we discuss imaging techniques and photometry.
-
Imagers and Filters
In this class we discuss imagers (in the sense of instruments capable to form and record an image) and filters. We focus on optical and near infrared. -
-
fits files
In this lecture, we see what the "fits" format is and we use a specific image as a test to see the basic functions of ds9.
-
Data reduction
In this lecture, we focus on the basic steps of data reduction (removing bias and flat), what they are and how to deal with them in IRAF (I promise, I am preparing how to do it with Python, spoiler, it's all here: https://ccdproc.readthedocs.io/en/latest/index.html ).
I also briefly comment on fringes, bad pixels (and bad columns).
-
CCD Characterisation
In this lecture, we overview the main characteristics of a CCD: readout noise, gain and linearity. We learn how to measure them and we insist on the importance of monitoring them.
-
Photometry
In this class, we go through the basic principle of photometry (in particular, aperture photometry).
We also discuss magnitudes (both Vega and AB) and calibrations.
-
Here is a series of tutorials that I prepared last year for the undergraduate course AGA0414.
They worked well last year and I expect they would work this yea as well.

Virtual Observatory
I was not thinking to speak about the Virtual Observatory so early but some tools which can be helpful for your test, are VO tools (Topcat and Aladin), so I offer you these slides which I prepared for Prof.Gastão's course http://www.astro.iag.usp.br/~gastao/aga0513/
