MHONGOOSE single-track moment maps

Abstract

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