Skymapper is useful to study galactic globular clusters ¶

Hi, I am fitting theoretical isochrones to photometry of galactic globular clusters. For some of them the SkyMapper DR2 photometry appears very useful, covering HB, RGB, TO and MS. However, for some other clusters DR2 is too shallow: data a magnitude deeper would be much better, specially in u and v filters. Should I wait for a (soon) next release with a deeper photometry, e.g. DR3, or any next release will be at same level of a limiting magnitude?
