MUSE HUDF survey I, Section 4: data and reproduction pipeline for photometry and astrometry
<p>Necessary data and <a href="http://akhlaghi.org/reproducible-science.html">Reproduction pipeline</a> for <a href="https://www.aanda.org/articles/aa/full_html/2017/12/aa30833-17/aa30833-17.html#S14">Section 4</a> of "<em>The MUSE Hubble Ultra Deep Field Survey: I. Survey description, data reduction and source detection</em>", Bacon et al. (2017), <a href="https://www.aanda.org/articles/aa/abs/2017/12/aa30833-17/aa30833-17.html">Astronomy & Astrophysics, 608, A1</a>. The purpose of this section in the paper is to show the photometric and astrometric precision of the processed <a href="http://muse-vlt.eu/science/">MUSE</a> 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).</p> <p>This repository on Zenodo contains all the necessary input data, software and <a href="http://akhlaghi.org/reproducible-science.html">reproduction pipeline</a> (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:</p> <ul> <li> <p><a href="https://zenodo.org/record/1163746/files/gnuastro-0.2.51-bc56.tar.gz"><code>gnuastro-0.2.51-bc56.tar.gz</code></a>: The version of <a href="https://www.gnu.org/software/gnuastro">GNU Astronomy Utilities</a> (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 <em>only</em> works with Gnuastro version 0.2.51, it will complain and abort if another version is installed.</p> <p>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 <a href="https://heasarc.gsfc.nasa.gov/FTP/software/fitsio/c/cfitsio3410.tar.gz">CFITSIO version 3.41</a> or earlier.</p> </li> <li> <p><a href="https://zenodo.org/record/1163746/files/gnuastro-dependencies.tar.gz"><code>gnuastro-dependencies.tar.gz</code></a>: 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).</p> </li> <li> <p><a href="https://zenodo.org/record/1163746/files/hst-acs-images.tar.gz"><code>hst-acs-images.tar.gz</code></a>: Necessary images from HST's <a href="https://archive.stsci.edu/prepds/xdf/">eXtreme Deep Field</a> survey <a href="https://archive.stsci.edu/pub/hlsp/xdf">archives</a>. 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.</p> </li> <li> <p><a href="https://zenodo.org/record/1163746/files/hst-acs-throughputs.tar.gz"><code>hst-acs-throughputs.tar.gz</code></a>: The throughputs of HST Advanced Camera for Surveys (ACS) filters necessary in this study. These are also available from the <a href="http://www.stsci.edu/hst/acs/analysis/throughputs/tables">HST archives</a> and are kept here with similar reasons to above.</p> </li> <li> <p><a href="https://zenodo.org/record/1163746/files/muse-pseudo-broadband-images.tar.gz"><code>muse-pseudo-broadband-images.tar.gz</code></a>: 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.</p> </li> <li> <p><a href="https://zenodo.org/record/1163746/files/reproduce-v1-4-gaafdb04.tar.gz"><code>reproduce-v1-4-gaafdb04.tar.gz</code></a>: The <a href="http://akhlaghi.org/reproducible-science.html">reproduction pipeline</a> (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 <a href="https://git-cral.univ-lyon1.fr/mohammad.akhlaghi/muse-udf-photometry-astrometry">git-cral.univ-lyon1.fr</a> or <a href="https://gitlab.com/makhlaghi/muse-udf-photometry-astrometry">gitlab.com</a>. 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 <code>README</code> 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).</p> </li> </ul> <p>The Creative Commons Attribution-NonCommercial 4.0 copyright mentioned in the Zenodo webpage is only applicable to files that don't have an explicit copyright within them.

The UltracoolSheet: Photometry, Astrometry, Spectroscopy, and Multiplicity for 4000+ Ultracool Dwarfs and Imaged Exoplanets
<p>The UltracoolSheet is a catalog of 4000+ ultracool dwarfs (spectral types M6 and later) and imaged exoplanets, including photometry, absolute astrometry, proper motions, parallaxes, multiplicity, spectroscopic classifications, memberships, and ages.</p> <p>The catalog lives in a Google spreadsheet at</p> <p> <a href="http://bit.ly/UltracoolSheet"><strong>http://bit.ly/UltracoolSheet</strong></a></p> <p>where it will receive future updates. The README tab in the spreadsheet contains a detailed description of the contents of the catalog.</p> <p>UltracoolSheet started as a catalog of all spectroscopically confirmed objects of spectral type L0 or later in the extended solar neighborhood (out to ~100 pc) that were known as of April 15, 2015. It has subsequently been extended to include many late-M dwarfs and also augmented with more recent discoveries spanning all ultracool spectral types.</p> <p>The component spreadsheets of UltracoolSheet are posted here as CSV files, along with summary figures and (.dat) files containing ASCII tables to simplify figure plotting for users. The Summary Plots.pdf file shows the sky map, age distribution, publication dates, and proper motion since publication for all objects in UltracoolSheet, as well as the distribution of projected separations of companions.</p> <p>When using data from the UltracoolSheet, please cite the individual papers from which the data comes. Citations codes are included for all the data in the tables, and the References table translates the citation codes into ADS bibcodes, Papers citekeys, and publication titles.</p> <p>For research that benefits from this compilation, please cite this Zenodo post and include the following acknowledgment:</p> <p>"This work has benefited from The UltracoolSheet at <a href="http://bit.ly/UltracoolSheet">http://bit.ly/UltracoolSheet</a>, maintained by Will Best, Trent Dupuy, Michael Liu, Aniket Sanghi, Rob Siverd, and Zhoujian Zhang, and developed from compilations by <a href="http://adsabs.harvard.edu/abs/2012ApJS..201...19D">Dupuy & Liu (2012)</a>, <a href="http://adsabs.harvard.edu/abs/2013Sci...341.1492D">Dupuy & Kraus (2013)</a>, <a href="https://ui.adsabs.harvard.edu/abs/2014ApJ...792..119D/abstract">Deacon et al.

Exoplanets Observing Methods I: Astrometry
<p>Recording of the presentation given at the Summer School</p>
Precise dynamical masses of new directly imaged companions from combining relative astrometry, radial velocities, and HIPPARCOS-Gaia eDR3 accelerations
<p>The VLT/SPHERE reduced images using the Geneva reduction pipeline, GRAPHIC, used to obtain the astrometry and photometry as published in Rickman et al. 2022. Each .fits file has been cosmetically corrected (i.e. bad pixels), background-subtracted, and flat-fielded. These files correspond to the 'flux frames' of the imaging observing sequence that was used to calculate the astrometry and photometry for each companion. The raw data are also available on the ESO archive with the relevant program numbers as listed in Rickman et al. 2022.</p>
Astrometry.net index files for astrometry on UVIT images
<p>The zip file contains the Astrometry.net index files used by the Ultraviolet Imaging Telescope Payload Operation Centre (UVIT POC) for performing astrometry on UVIT images. It includes the 5200, 6000, and 6100 series index files distributed by the Astrometry.net software team (available at <a href="http://data.astrometry.net/" target="_new" rel="noreferrer">http://data.astrometry.net/</a>). Additionally, it contains the index files generated by Akanksha et al. (in preparation). Please note that the UVIT POC currently does not use the 6000 and 6100 series index files, but these files may still be useful for some UVIT fields.</p>
