     "This Notebook demonstrates how to run the source detection, measurment, and deblending algorithms with a focus on optimizing for low-surface brightness object detection. It attempts to split out the source detection and measurement algorithms from `processCCD` and apply them to the search for low surface brightness galaxies. The content of this notebook builds off of an analysis from Johnny Greco, adapted into notebook form in Robert Lupton's [Greco LSB.ipynb](https://github.com/RobertLuptonTheGood/notebooks/blob/master/Demos/Greco%20LSB.ipynb). Some source detection and measurement details come from [Tune Detection.ipynb](https://github.com/RobertLuptonTheGood/notebooks/blob/master/Demos/Tune%20Detection.ipynb) and [Kron.ipynb](https://github.com/RobertLuptonTheGood/notebooks/blob/master/Demos/Kron.ipynb).\n",
