Stile: the Systematics Tests In LEnsing pipeline


Installation instructions

Stile is a pure python package, no compilation needed. You can install it using:

python setup.py install

Dependencies

To run Stile, you must have:

  • Python 2.7
  • NumPy

We also recommend:

  • TreeCorr, Mike Jarvis's 2-point correlation function code. All of our correlation function tests involve calls to this package.
  • PyFITS/Astropy to handle FITS tables and images. Stile can run on ASCII tables, but is much slower.
  • matplotlib to generate plots.

More dependencies may be added in the future.


Documentation

The documentation is available online at http://stile.readthedocs.io/. You can also build it using Sphinx in the doc/ directory.


Current functionality

Right now, Stile can:

  • Generate an average shear signal around a set of points (if you've installed corr2), given two catalogs that you specify in a particular way, and plot the results (if you have matplotlib).
  • Perform a number of basic statistics measurements and print the results.
  • Make whisker plots.
  • Make scatter plots with trendlines.
  • Generate histograms.
  • Perform any of the above tests for data with different binning schemes applied, using a simple method of specifying the bins.
  • Interface with sufficiently recent versions of the HSC pipeline.

Wishlist

Over the upcoming months, we plan to add:

  • A more flexible way of specifying your data set than hard-coding the file names in your script.
  • Automatic drivers to run as many tests as your data set allows.
  • A larger suite of example code.
  • Tests on images, and the utilities to make those tests easier.
