WebApr 14, 2024 · Aperture Photometry is the act of summing up the values of all the pixels in a pre-defined aperture as a function of time. By carefully choosing the shape of the aperture mask, you can avoid nearby contaminants or improve the strength of the specific signal you are trying to measure relative to the background. WebSetup¶. In order to be able to use PP anywhere on your machine, you have to add the full path of the photometrypipeline/ directory to your PYTHONPATH and PATH variables, and you have to create a PHOTPIPEDIR variable on your system that points to the same directory (include these commands in your .bashrc, .cshrc, or .profile file.)
