About

almaqso is an automated package for downloading and analyzing ALMA calibration sources (quasars). Originally developed for analyzing absorption lines, this package addresses a limitation of the standard calibration scripts attached to ALMA archive data, which often mask absorption lines. By generating calibration scripts that preserve these lines, this package ensures accurate analysis of absorption features.

Pre-requisites

Developer Guide

Pre-requisites

You do not have to install all shown below. Please install only what you need.

• uv: Strongly recommended. uv will manage everything about Python.
• plantuml & graphviz: Install if you want to build docs or re-render the docs/diagrams.
• imagemagick: Install if you want to build PDF version documentation.

You can reproduce the environment with uv:

uv sync --dev

Then, you can run main.py or something with

uv run main.py  # or something

Render diagrams

(Re-)Render all PUML files in docs/diagrams with the command below. SVG files will be generated in the same directory.

plantuml --svg docs/diagrams/

This is run by documentation building scripts below.

Build documentation

If you change the files in docs/diagrams, please recreate the SVG files first as written in Render diagrams section.

HTML:

./scripts/sphinx-build-html.sh

If you do not use uv, run with python instead:

python sphinx-build -b html docs docs/_build/html

Then, please open docs/_build/html/index.html in your browser.

PDF: The script file will build PDF file and copy it to docs/almaqso.pdf.

./scripts/sphinx-build-pdf.sh
