WebThe Photometry Pipeline (PP) is a Python software package for automated photometric analysis of imaging data from small to medium-sized observatories. It uses Source Extractor and SCAMP to register and photometrically calibrate images based on catalogs that are available online; photometry is measured using Source Extractor aperture photometry ... 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.) diabetic can\u0027t sleep at night https://triplebengineering.com
