You have found the GitHub Organization for the Open mulTiwavelength Transient Event Repository (or OTTER)!

Each repo is for a different part of the project tentatively structured as follows:

1. Set the OTTER_ROOT environment variable

   export OTTER_ROOT=/path/to/where/to/clone
   

2. Clone the relevant repos:

   git clone https://github.com/astro-otter/otter.git $OTTER_ROOT/otter
   git clone https://github.com/astro-otter/otterdb.git $OTTER_ROOT/otterdb
   

3. Install the NASA ADS Python API by following the instructions at https://ads.readthedocs.io/en/latest/#getting-started
4. Install otter, the API for this database. From the root directory where you installed these repos:

   cd $OTTER_ROOT/otter
   python -m pip install -e .
   

5. Process the data to build the local "database" (although it is really just a directory). Then, you can build the "database" by running the following commands:

   cd $OTTER_ROOT/otter/scripts/
   python3 gen_summary_table.py --otterroot $OTTER_ROOT
   

6. Easily access the data using the Otter code! In python:

import os
from otter import Otter
otter = Otter(os.path.join(os.environ['OTTER_ROOT'], 'otterdb', '.otter'))
res = otter.query(names='AT2018hyz')
print(res)
