ALminer: ALMA archive mining and visualization toolkit

ALminer: ALMA Archive Mining & Visualization Toolkit

alminer is a Python-based code to effectively query, analyse, and visualize the ALMA science archive. It also allows users to directly download ALMA data products and/or raw data for further image processing.

Installation

The easiest way to install alminer is with pip:

pip install alminer

To obtain the most recent version of the code from Github:

pip install https://github.com/emerge-erc/ALminer/archive/refs/heads/main.zip

Or clone and install from source:

# If you have a Github account:
git clone [e-mail]:emerge-erc/ALminer.git
# If you do not:
git clone https://github.com/emerge-erc/ALminer.git

# After cloning:
cd ALminer
pip install .

Note that depending on your setup, you may need to use pip3.

Dependencies

The dependencies are numpy, matplotlib, pandas, pyvo, astropy version 3.1.2 or higher, and astroquery version 0.4.2.dev6649 or higher. We only use the astroquery package for downloading data from the ALMA archive. The strict requirement to have its newest version is due to recent changes made to the ALMA archive. alminer works in Python 3.

Getting started

We have created an extensive tutorial Jupyter Notebook where all alminer features have been highlighted. This is an excellent starting point to get familiar with all the possibilities; a glossery of all functions is provided at the bottom of this notebook.

To work with the tutorial notebook interactively

We highly recommend working in a Jupyter notebook environment in order to make use of alminer's visualization tools. We aim to keep adding new notebooks relevant for various sub-fields in the future.

Note that the Jupyter notebooks may be outdated. The most up-to-date information can be found on the documentation page.

Documentation

More information can be found in the documentation.

What's new:

• You can now specify which archive mirror to download data from: ESO is the default, and other options are NRAO and NAOJ. This option can be given through the 'archive_mirror' parameter in the download_data function.
• You can now specify which archive service to query: ESO is the default, and other options are NRAO and NAOJ. This option can be given through the 'tap_service' parameter to all functions that do the query (e.g. keysearch, target, catalog). For example:
  • alminer.target(["TW Hya", "HL Tau"], tap_service='NRAO')
  • Note that currently the ESO service is not returning all results, hence it is advisable to test your queries with multiple services until further notice.
• It is now possible to query entire phrases with the keysearch function. For example:
  • alminer.keysearch({'proposal_abstract': ['"high-mass star formation" outflow disk']}) will query the proposal abstracts for the phrase high-mass star formation AND the words outflow AND disk.
  • alminer.keysearch({'proposal_abstract': ['"high-mass star formation" outflow disk', '"massive star formation" outflow disk']}) will query the the proposal abstracts for the phrase high-mass star formation AND the words outflow AND disk OR the phrase massive star formation AND the words outflow AND disk.
