In this section we learn how to stack and reduce FITS images using the CCDproc package. Stacking is especially useful if you have images which are polluted with a lot of noise. We will also be reducing image with bias correction, dark subtraction, and field fielding.
Now, let us begin with importing all the packages we need.
You would next need a dark image to work with to remove the dark current in the image.
Next we’re going to do a bias correction.
Now that we have both dark and bias, we want to add on flat correct:
Next, we can finally dark subtract and flat field the image:
