Demonstration prepared for the MidPoint Review of LINCC Frameworks, Pittsburgh, 2025. This demo showcases working with HATS-partitioned survey catalogs via LSDB.
- Slide deck
- LSDB (on GitHub) (on ReadTheDocs)
- HATS (on GitHub) (on ReadTheDocs)
- nested-dask (on GitHub) (on ReadTheDocs)
- nested-pandas (on GitHub) (on ReadTheDocs)
You can follow along with this demo by creating your own local environment.
If installing in your own hardware, create a virtual environment and install the relevant packages:
>> conda create --name lincc python=3.12
>> conda activate lincc
>> pip install lsdb pyvo ipyaladin cesium scikit-learn aiohttp
In this notebook we will learn how to:
- Load object and source catalogs (lazily)
- Perform crossmatching with existing
LSDBcatalogs - Save the results of a science workflow to disk
