TailZ wiki

Probing the sparse tails of redshift distributions

Contributors: bengranett

Introduction

Tailz is a code for estimating the redshift distributions of photometric samples of galaxies. It uses a Voronoi tessellation density estimator to interpolate the distribution and performs well even in the tails.

News

The article describing the algorithm is now on arXiv.

Examples

• Single Gaussian
• VIPERS
• Use of the python module interface

Installation

Download the current version of TailZ from the project repository.

Tailz may be installed in your user account with:

python setup.py install --user

See more in the install guide. Tailz was developed with python2.7 and is not compatible with python3.

The following python packages must also be installed:

• numpy
• scipy
• scikit-learn
