SPECTRUM D2.3 Dissemination, Communications and Exploitation - Final Report
Authors: Franck, Gwen, Xavier, Salazar
Type: Project deliverable
Published: 2026-07-30
Keywords: Dissemination, communication, exploitation, high energy physics, radio astronomy, key exploitable results

<p>This report presents the final outcomes of the dissemination, communication, and exploitation activities conducted during the 30-month runtime of the SPECTRUM project (January 1, 2024 – June 30, 2026). Operating as a Coordination and Support Action (CSA) , the project successfully built a structured Dissemination, Communication, and Engagement (DCE) framework to maximize the visibility and long-term impact of its Key Exploitable Results (KERs). </p>
The velocity field of the Scorpius-Centaurus OB association
Authors: Hutschenreuter, Sebastian
Type: Dataset
Published: 2026-07-30

<h2>General information</h2>
<p>The maps in this record are the posterior mean and standard deviations for the stellar velocity field of Sco-Cen as published in Hutschenreuter et al. (<a href="https://arxiv.org/abs/2509.13607">https://arxiv.org/abs/2509.13607</a> / <a href="https://www.aanda.org/articles/aa/pdf/2026/01/aa57273-25.pdf">A&A</a>), as well as the corresponding latent space samples to reproduce these quantites using the model at <a href="https://github.com/shutsch/ScoCen25">https://github.com/shutsch/ScoCen25</a> .</p>
<p>Illustrations of the maps can be found at <a href="https://shutsch.github.io/sco_cen_data.html">https://shutsch.github.io/sco_cen_data.html.</a></p>
<h2>File Description</h2>
<p>The maps are published in hdf5 format, see https://docs.h5py.org/en/stable/index.html for details. </p>
<p>All quantities are expressed in heliocentric Galactic Cartesian coordinates x, y, z on a 70 × 70 ×50 grid with voxel size 3^3 pc^3, anchored at (x_o, y_o, z_o) = (−5, −190, −65) pc. Vector fields will have the shape (3, 70, 70, 50), scalar fields (70, 70, 50).</p>
<p>The velocity fields are expressed in km/s the barycentric reference frame, in order to a convert to a Sco-Cen frame subtract the field with (v_x,sc, v_y,sc, v_z,sc) = (−6.2, −20.0, −5.4) km/s. </p>
<p>The derivative fields are reference frame independent and in units of 1/Myr.</p>
<p>The flow related files contains two hdf5-data sets called <code>mean</code> and <code>std</code>, containing the posterior mean and standard deviation, respectively. </p>
<p>All maps can be reproduced using the latent space samples and the model the model at <a href="https://github.com/shutsch/ScoCen25">https://github.com/shutsch/ScoCen25</a>, see the README there for more info.</p>
<p>Additionally, we publish boolean stellar density based masks, which we use as a proxy for the boundary of Sco-Cen.  See the paper for a detailed description on their definition.</p>
