This repository has Jupyter Notebook examples of data reduction for the Gemini Observatory instruments. They were written using the DRAGONS' Application Program Interface (API) for Python.
-
Install the Python-based DRAGONS platform by creating an anaconda environment. Detailed instructions can be found on the Gemini Data Processing Software webpage.
-
At this point, you will have DRAGONS installed. To run the notebooks in the US NGO repository, you will have to allow the Jupyter notebooks to run on your Conda DRAGONS environment. You can do that by installing the packages listed below. From your bash terminal:
conda install -n dragons nb_conda_kernels ipykernel -
The Jupyter Notebooks are configured to download the raw (public) data directly from the Gemini Observatory Archive. For that, you'll need the
wgetpython package installed. From your bash terminal:conda install -n dragons wget -
Download one of the files listed on the Current notebooks available section. Once the download is completed, start a bash terminal, go to the folder where you have downloaded the file, and type:
conda activate dragons jupyter notebook [name].ipynb
Note: at this stage, a browser window will open and the Jupyter notebook will be loaded. On the top right part of the window, you should see Python [conda env:dragons] or something similar, ensuring that the correct DRAGONS environment is loaded.
