GROWTH Target of Opportunity Marshal

This is the manual for the GROWTH Target of Opportunity Marshal, or ToO Marshal for short. It is a platform that has been developed by the Global Relay of Observatories Watching Transients Happen (GROWTH) collaboration in order to coordinate follow-up observations of multimessenger transients. The ToO Marshal’s responsibilities include:

  1. Ingest alerts for astrophysical multimessenger transients from LIGO/Virgo, IceCube, Fermi, Swift, and other experiments.

  2. Notify on-duty GROWTH astronomers when multimessenger transients occur that meet triggering criteria for science programs.

  3. Plan optimal observations for a heterogeneous network of ground-based telescopes including ZTF, DECam, KPED, Gattini, and GROWTH-India.

  4. Submit observations to robotic telescope queues and monitor the progress of observations.

  5. Provide a central interface for vetting candidates from these facilities in combination with external data sources including the Census of the Local Universe (CLU) galaxy catalog.

  6. Automatically compose GCN Circular astronomical bulletins.


Caveat emptor: This repository has been made publicly available in the spirit of open-source software. However, much of the code is very specific to the particular facilities, instruments, and data sources that we are using, and may not be immediately generalizable.
