BlendingToolKit (BTK) generates images of blended objects and evaluate performance metrics on various detection, deblending and measurement algorithms. The toolkit is a convenient way to produce multi-band postage stamp images of blend scenes and evaluate the performance of deblending algorithms, as well as train samples for machine learning algorithms.

qp manipulates parametrizations of 1-dimensional probability distribution functions, as suitable for photo-z PDF compression. The code helps determine a parameterization for storing a catalog of photo-z PDFs that balances the available storage resources against the accuracy of the photo-z PDFs and science products reconstructed from the stored parameters.
