Getting the data from sources

Setup

You'll need a modern unix-like environment (with git and git-lfs) where Anaconda can be installed:

wget https://repo.anaconda.com/archive/Anaconda3-2024.02-1-Linux-x86_64.sh
sh Anaconda3-2024.02-1-Linux-x86_64.sh

(First time only) Get this repo and clone the conda environment:

git clone https://github.com/profjsb/astrocompress.git
cd astrocompress
mkdir -p data/integer/imaging/sci/
conda env create --file astrocompress.yaml

Activate the environment:

conda activate astrocompress

Download the SDSS Data Cubes

You'll need to get the large CSV containing the list of the SDSS data fields:

cd sources/SDSS
git lfs pull --include "Stripe82Fields.csv"

Now get a sample of cubes. For example:

python ./make_sdss_cubes.py  -m None --size="(800,800)" --random_state=42 -n 2

See the documentation in make_sdss_cubes.py for command-line arguments.

Download the Keck data

cd sources
python download.py

This will do a trial run. To pull all the data:

python download.py --full
