GDT-CGRO

The GDT-CGRO is an extension to Gamma-ray Data Tools that adds functions specific to the CGRO mission.

Normal Installation

If you don't plan to contribute code to the project, the recommended install method is installing from PyPI using:

pip install astro-gdt-cgro
gdt-data init

The gdt-data init is required to initialize the library after installation of astro-gdt. You do not need to perform the initialization again if astro-gdt was already installed and initialized. There is no harm in running it again "just in case".

Writing Extensions using Namespace Packaging

This is an extension to astro-gdt and should should contain a directory 'gdt' with a subdirectory 'missions' which will hold the extension code in a package directory named after the mission.

For example, GDT-CGRO has the following directory layout:

.
├── config
├── dist
├── docs
├── src
│   └── gdt
│      └── missions
│          └── cgro
│              └── __init__.py
└── tests
  └── missions
      └── cgro

Since GDT-CGRO uses namespace packaging, both src/gdt and src/gdt/missions do not contain a file named __init__.py. This is because they are Namespace packages.

Notice that directory src/gdt/mission/CGRO contains an __init__.py file signalling to Python that those directories are regular packages.

You can learn more about Namespace packages by reading PEP-420.

Helping with Documentation

You can contribute additions and changes to the documentation. In order to use sphinx to compile the documentation source files, we recommend that you install the packages contained within requirments.txt.

To compile the documentation, use the following commands:

cd $PROJ_ROOT/docs
make html
