MHONGOOSE single-track moment maps

<h2>MHONGOOSE single-track moment maps</h2> <p>This repository contains all MHONGOOSE single-track moment maps as described in de Blok et al. (2024).</p> <p>For each galaxy, two resolutions are provided, derived with robust parameter 0.5 and 1.5, respectively. The<br>former highlights small-scale structures at the cost of a reduced column density sensitivity, the<br>latter emphasises low column density structures.</p> <p>For each galaxy and resolution we provide:</p> <ul> <li>zeroth moment map (mom0) - integrated HI intensity map</li> <li>primary-beam-corrected zeroth moment map (mom0_pb)</li> <li>first moment map - intensity-weighted mean velocity field</li> <li>second moment map (mom2) - velocity spread map</li> <li>number of channels (nchan) contributing to each pixel</li> </ul> <p>Average properties of the observations are given below. Beam sizes for the individual galaxies areprovided in the headers.</p> <table> <tbody> <tr> <td>robust value</td> <td>pixel size (arcsec)</td> <td>beam (arcsec)</td> <td>noise (mJy/beam)</td> <td>log(NHI) (cm-2) [1sigma; 1 chan]</td> <td>log(NHI) (cm-2) [3sigma; 16 km/s]</td> </tr> <tr> <td>1.5</td> <td>7</td> <td>30</td> <td>0.49</td> <td>17.94</td> <td>18.94</td> </tr> <tr> <td>0.5</td> <td>3</td> <td>12</td> <td>0.54</td> <td>18.79</td> <td>19.79</td> </tr> </tbody> </table> <p>For a full description of the derivation of the moment maps see de Blok et al (2024).</p>
