- BlendingToolKit (btk) requires an input catalog that contains information required to simulate galaxies and blends. This repository includes sample input catalogs with a small number of galaxies that can be used to draw blend images with btk. See tutorials to learn how to run btk with these catalogs.
- Catalog corresponding to one square degree of sky and pre-processed WeakLensingDeblending catalogs can be downloaded from here.
The code is intended to run in python >=3.6. To run btk you need to install
- WeakLensingDeblending
- GalSim
- numpy
- astropy
- fitsio
- scipy
- lmfit
More detailed installation instructions can be found here.
The tutorials include examples of using btk with some detection, deblending or measurement packages including
