MUSE HUDF survey I, Section 4: data and reproduction pipeline for photometry and astrometry

Akhlaghi, Mohammad; Bacon, Roland

Necessary data and Reproduction pipeline for Section 4 of "The MUSE Hubble Ultra Deep Field Survey: I. Survey description, data reduction and source detection", Bacon et al. (2017), Astronomy & Astrophysics, 608, A1. The purpose of this section in the paper is to show the photometric and astrometric precision of the processed MUSE 3D data cubes discussed in the paper (pseudo-broad-band images created from the cubes) in comparison with broad-band images of the Hubble Space Telescope (HST).

This repository on Zenodo contains all the necessary input data, software and reproduction pipeline (containing the scripts, configuration files and settings to exactly reproduce the results in Section 4 of the paper). Below is a description of the contents:

  • gnuastro-0.2.51-bc56.tar.gz: The version of GNU Astronomy Utilities (Gnuastro) that is necessary for this pipeline. Gnuastro is a large collection of programs for astronomical data analysis on the command-line (and in scripts). Note that the reproduction pipeline only works with Gnuastro version 0.2.51, it will complain and abort if another version is installed.

    IMPORTANT NOTE: Since version 0.2.51 of Gnuastro was released, CFITSIO (one of Gnuastro's dependencies) has added a dependency for the cURL library (to read https URLs). Therefore, to install Gnuastro 0.2.51, please install CFITSIO version 3.41 or earlier.

  • gnuastro-dependencies.tar.gz: Software libraries necessary to build Gnuastro as it is used here. With these, a working C compiler is enough (currently only tested in a GNU/Linux environment) to exactly reproduce the results (tables).

  • hst-acs-images.tar.gz: Necessary images from HST's eXtreme Deep Field survey archives. These images are not necessary to run the reproduction pipeline (they will be downloaded from the HST archives if not present). They are stored here for the self-sufficiency of this repository and faster download: in this lossless compressed format, they are roughly 1/3rd the volume of the same files in HST archives.

  • hst-acs-throughputs.tar.gz: The throughputs of HST Advanced Camera for Surveys (ACS) filters necessary in this study. These are also available from the HST archives and are kept here with similar reasons to above.

  • muse-pseudo-broadband-images.tar.gz: Pseudo-broad-band images generated from the MUSE 3D data cube. These images are only released in this repository. However, to run the reproduction pipeline, it isn't necessary to download them directly from here. The script will download them from Zenodo automatically.

  • reproduce-v1-4-gaafdb04.tar.gz: The reproduction pipeline (version 1-4-gaafdb04) that produces the results (tables) plotted in the paper. The full Git version controlled history of this repository is available on or We recommend cloning from the Git repository if it is available. This tarball is kept here in case those servers don't work or Git is no longer in common use. Please see the README file in this repository for instructions on how to run the reproduction pipeline and exactly reproduce the results. This pipeline will download all the necessary data if they aren't already present on the system (it is probably just necessary to install the required version of Gnuastro).
