We do so by simulating the process of assembling a spectroscopic sample (including observer-assigned confidence flags) and highlight the impacts of spectroscopic target selection and redshift failures.

pyro is a Python-based simulation framework designed for ease of implementation and exploration of hydrodynamics methods.
INSTRUMENTATION AND METHODS FOR ASTROPHYSICS COMPUTATIONAL PHYSICS
We employ a special type of Convolutional Neural Network, the U-Net, that enables the classification of clean signal and RFI signatures in 2D time-ordered data acquired from a radio telescope.
INSTRUMENTATION AND METHODS FOR ASTROPHYSICS
We present a new model for the distribution of free electrons in the Galaxy, the Magellanic Clouds and the intergalactic medium (IGM) that can be used to estimate distances to real or simulated pulsars and fast radio bursts (FRBs) based on their dispersion measure (DM).
ASTROPHYSICS OF GALAXIES
Our model, Prospector-$\alpha$, includes dust attenuation and re-radiation, a flexible attenuation curve, nebular emission, stellar metallicity, and a 6-component nonparametric star formation history.
ASTROPHYSICS OF GALAXIES
We present the first stable release of Halotools (v0. 2), a community-driven Python package designed to build and test models of the galaxy-halo connection.

The algorithm behind emcee has several advantages over traditional MCMC sampling methods and it has excellent performance as measured by the autocorrelation time (or function calls per independent sample).
INSTRUMENTATION AND METHODS FOR ASTROPHYSICS COMPUTATIONAL PHYSICS COMPUTATION
We discuss the implementation ofJANUS and present tests of its accuracy and speed by performing and analyzing long-term integrations of the Solar System.
INSTRUMENTATION AND METHODS FOR ASTROPHYSICS COSMOLOGY AND NONGALACTIC ASTROPHYSICS EARTH AND PLANETARY ASTROPHYSICS
We have built a reliable and robust system that takes as input an astronomical image, and returns as output the pointing, scale, and orientation of that image (the astrometric calibration or WCS information).
INSTRUMENTATION AND METHODS FOR ASTROPHYSICS
The Astropy project supports and fosters the development of open-source and openly-developed Python packages that provide commonly-needed functionality to the astronomical community.
