Demonstration prepared for the ADASS 2024 conference, Valletta, 2024. This demo showcases working with HATS-partitioned survey catalogs via LSDB, and time domain analysis with nested-dask.
- Slide deck (Work in progress)
- LSDB (on GitHub) (on ReadTheDocs)
- HiPSCat (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
In this notebook we will learn how to:
- Query and filter catalog data
- Compute time-series features for LSDB catalogs using
nested-dask - Plot light curves and periodograms
In this notebook we will learn how to:
- Use VizieR TAP query to access tables and store/handle them in
LSDB - Use those catalogs to perform crossmatching with existing
LSDBcatalogs - Perform time-series analysis and exploration with
nested-dask
Watch the following LINCC Tech Talk to learn more about LSDB. Other relevant talks can be found in the LSST Discovery Alliance website.
