om10's Introduction

OM10

Tools for working with the Oguri & Marshall (2010) mock catalog of strong gravitational lenses

Installing OM10

pip install om10

Developing OM10

Fork the repo and clone it to your local machine. Then, do

python setup.py develop

Now when you import om10 you'll get the development version, linked to to your fork.

Make sure you have all the requirements with

conda install scipy>=0.18.1
pip install -r requirements.txt

A high version of scipy is needed for scikit-learn. We also use Tom Collett's lenspop package, currently in beta.

Example Use

Read in the master FITS catalog and look up one system:

db = om10.DB(catalog="data/qso_mock.fits")

id = 7176527
lens = db.get_lens(id)

Make a plot of it:

om10.plot_lens(lens)

Select a mock LSST sample:

db.select_random(maglim=23.3,area=20000.0,IQ=0.7)
print db.sample
