lfkit.utils.download_poggianti97_data module#

Download Poggianti (1997) correction tables from VizieR.

This script retrieves the Poggianti (1997) catalog (J/A+AS/122/399) using astroquery and stores the tables as CSV files inside the LFKit package data directory:

src/lfkit/data/poggianti1997/

The downloaded files are written in CSV format so they can be accessed at runtime via importlib.resources.

To run this script, simply execute it from the command line:

python scripts/download_poggianti97_data.py

This script is intended to be run manually during development or data refresh.

lfkit.utils.download_poggianti97_data.main()[source]#

Fetch the Poggianti (1997) catalog and save tables as CSV files.

The VizieR catalog may contain multiple tables (e.g., k-about, e-about). Each table is written to the LFKit package data directory using its short table name as the filename.

The output directory is created if it does not already exist, and minimal __init__.py files are ensured so the directory is importable as a package resource.

Return type:: None
