This project provides Python code allowing to search for extended sources in Chandra X-ray Observatory ACIS images using DBSCAN cluster detection algorithm. The python code uses Bokeh library to produce a convenient and interactive graphical user interface (GUI) which will run on Bokeh server in user's default browser (Chrome is recommended). The clustering search is done on-the-fly by selecting the desired algorithm and visualization parameters in the GUI. The outcome of the search is shown graphically as well as in the tabular form. It includes the coordinates of found extended sources and their detection significances. The corresponding regions can be exported in SAO DS9 format.
The app can be run on Binder without installation:
- Clone this repo and
cd ChaSES
- [optional] Create environment
mamba create -n ChaSES
mamba activate ChaSES
- Install dependencies
mamba env update --file environment.yml
- Run Bokeh server
bokeh serve app/main.py --show
Selected 1042 Chandra ACIS ObsIDs with point sources removed are available at 🤗 Hugging Face:
