MHONGOOSE single-track moment maps

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. The
former highlights small-scale structures at the cost of a reduced column density sensitivity, the
latter 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.

For a full description of the derivation of the moment maps see de Blok et al (2024).
