LSDB Rubin

Suite of utilities for interacting with Rubin LSST data within LSDB.

Quickstart

To install, clone the repository (ideally, within a virtual environment):

git clone https://github.com/astronomy-commons/lsdb-rubin.git
cd lsdb-rubin
pip install .

LSST tract/patch search

Use LSDB to search catalogs by LSST tract and/or patch.

import lsdb
import skymap_convert
from lsdb_rubin import tract_patch_search

gaia = lsdb.read_hats("https://data.lsdb.io/hats/gaia_dr3/gaia")
lsst_skymap = skymap_convert.ConvertedSkymapReader(preset="lsst_skymap")

tract_index = 10_000
lsdb.catalog.Catalog.tract_patch_search = tract_patch_search
gaia.tract_patch_search(skymap_reader=lsst_skymap, tract=tract_index)

See the demo notebook for more.

Plot a LSST light curve

LSST light curves can be tricky to plot, so we've provided an easy method for a single light curve.

import lsdb
from lsdb_rubin.plot_light_curve import plot_light_curve

dia_object = lsdb.open_catalog("<your-path-to>/lsdb-rubin/tests/data/mock_dp1_1000")
dia_object = dia_object.compute()

plot_light_curve(dia_object.iloc[0]["diaObjectForcedSource"])

See the demo notebook for more.
