    breaker contour <gwid> <ra> <dec>

    COMMANDS
    --------
    init                  setup the breaker settings file for the first time
    update                update the PS1 footprint table in breaker database and associate with GW-IDs. Optionally download overlapping NED source and also add to the database
    skymap                generate an all sky FITS & PDF image map given the path to the LV likeihood map (Meractor and Mollweide projections respectively)
    plot                  enter plotting mode
    timeline              plot from the epoch of the wave detection forward in time
    history               plot from now back in time over the last days, weeks and months
    comparison            produce a multi-panel plot to compare wave maps
    stats                 generate some coverage stats for a given wave survey campaign
    sources               overplot map with NED sources found within the wave campaign footprint
    faker                 generate a catalogue of simulated transient sources in PS1 exposure ID footprint
    listen                connect to grace DB and download maps found within the given time range
    contour               determine within which likelihood contour a given transient location lies (nearest 10%)

    ARGUMENTS
    ---------
    ra                    right ascendsion (sexegesimal or decimal degrees)
    dec                   declination (sexegesimal or decimal degrees)
    far                   false alarm rate limit in Hz. Default *1e-5* (~= 1 per day)
    -w <gwid>             the gravitational wave ID (graceDB or human-readable GW forms allowed)
    pathToSettingsFile    path to the yaml settings file
    -c <centerDeg>        the central longitude line (deg)
    pathToMapDirectory    path to a directory containing localisation maps
    ps1ExpId              a panstarrs exposure ID
    mjdStart              start of an MJD range
    mjdEnd                end of the MJD range
    inLastNMins           in the last N number of minutes
    pathToLVMap           path to the LV likelihood map
    sec                   time in seconds
    -t <telescope>        select an individual telescope (default is all telescopes) [ps1|atlas]
    -p <projection>       skymap projection. Default *mercator*. [mercator|gnomonic|mollweide]

    FLAGS
    -----
    -h, --help            show this help message
    -s, --settings        the settings file
    -n, --updateNed       update the NED database steam
    -d, --daemon          listen in daemon mode
    -a, --all             plot all timeline plot (including the CPU intensive -21-0 days and all transients/footprints plots)
    -P, --no-pointings    do not update pointings

Documentation

Documentation for breaker is hosted by Read the Docs (last stable version and latest version).

Installation

The easiest way to install breaker is via Anaconda. For some instructions for installing Anaconda see here.

Once you have Anaconda installed, then create and activate a new conda environment:

conda create -n breaker python=2.7 pip
source activate breaker

Now do a conda install of healpy before installing breaker (the pip install of healpy seems very flaky):

conda install -c conda-forge healpy

Finally install breaker:

pip install breaker

Installion a Development Version

Or you can clone the github repo and install from a local version of the code:

git clone [e-mail]:thespacedoctor/breaker.git
cd breaker
python setup.py install

To upgrade to the latest version of breaker use the command:

pip install breaker --upgrade

Troubleshooting

If you’re having trouble with the installation here are a few things to try:

Astropy and Clang. On Mac OS you may have to set your C-compiler to clang before astropy will install. So before the breaker installation, try:

setenv CC clang

or, for bash:

export CC=clang

Then try and install breaker again.

healpy. If you’re having trouble installing healpy try installing the latest version from github. Download and extract the tarball.

Untar, set your MACOSX_DEPLOYMENT_TARGET environment variable and install:

tar -xvf healpy-1.9.0.tar.gz
cd healpy-1.9.0
setenv MACOSX_DEPLOYMENT_TARGET 10.11
python setup.py install

Development

If you want to tinker with the code, then install in development mode. This means you can modify the code from your cloned repo:

git clone [e-mail]:thespacedoctor/breaker.git
cd breaker
python setup.py develop
