## About

`almaqso` is an automated tool 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

### CASA

Please use [CASA](https://casa.nrao.edu/) **with ALMA pipeline**.
Version 6 is only supported.
I am using `CASA version 6.6.6-17-pipeline-2025.1.0.35`.

### CASA Modules

Please install [analysisUtilites](https://zenodo.org/records/17252072).
I strongly recommend you to use the **LATEST** version of it.

## Installation

```shell
pip install almaqso
```

## Developer Guide

### Pre-requisites

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

- [uv](https://github.com/astral-sh/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:

```shell
uv sync --dev
```

Then, you can run `main.py` or something with

```shell
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.

```shell
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:**
```shell
./scripts/sphinx-build-html.sh
```
If you do not use uv, run with python instead:
```shell
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`.

```shell
./scripts/sphinx-build-pdf.sh
```

<!-- When you need to reproduce the `almaqso.rst` file with the change of codes,
```shell
uv run sphinx-apidoc -o docs almaqso
``` -->
