In the subsections below, first a review of some very basic information and concepts behind modeling a real astronomical image is given. You can skip this subsection if you are already sufficiently familiar with these concepts.
|• Defining an ellipse:||An ellipse on a pixelated grid.|
|• PSF:||Radial profiles for the PSF.|
|• Stars:||Making mock star profiles.|
|• Galaxies:||Radial profiles for galaxies.|
|• Sampling from a function:||Sample a function on a pixelated canvas.|
|• Oversampling:||Oversampling the model.|
