Early Observations of the MHONGOOSE Galaxies: Getting Ready for MeerKAT
  We present early observations of 20 galaxies in the MHONGOOSE survey galaxies
using KAT-7, the GBT, and MeerKAT. We present the best calibrators for five of
the MHONGOOSE galaxies observed with the KAT-7, and search for signs of gas
accretion in the GBT data, down to $3\sigma$ column density levels of $\rm
2.2\times10^{18}\, cm^{-2}$ over a $\rm 20\, km\, s^{-1}$ linewidth, but
identify none. Using the KAT-7 and MeerKAT data, we have derived rotation
curves and mass models for NGC 3621 and NGC 7424 out to an unprecedented
extent. As a precursor to the SKA, the MeerKAT telescope combines both a high
spatial resolution and a large field of view, necessary to map the extended
neutral hydrogen in local galaxies. The mass models of the two galaxies were
constructed for both the Dark Matter (DM) models (the pseudo-isothermal model
and the Navarro-Frenk-White model) and MOND. Overall, we find that the DM
models provide a better fit than MOND to the galaxies' rotation curves.
Furthermore, the pseudo-isothermal model is found to be the most consistent
with the observations.
