We present deep optical photometry from the DECam imager on the 4m Blanco telescope of over 12 deg ^ { 2 } around the Carina dwarf spheroidal , with complete coverage out to 1 degree and partial coverage extending out to 2.6 degrees .
Using a Poisson-based matched filter analysis to identify stars from each of the three main stellar populations , old , intermediate , and young , we confirm the previously identified radial age gradient , distance , tidal radius , stellar radial profiles , relative stellar population sizes , ellipticity , and position angle .
We find an angular offset between the three main elliptical populations of Carina , and find only tentative evidence for tidal debris , suggesting that past tidal interactions could not have significantly influenced the Carina dwarf .
We detect stars in the vicinity of , but distinct to , the Carina dwarf , and measure their distance to be 46 \pm 2 kpc .
We determine this population to be part of the halo of the Large Magellanic Cloud at an angular radius of over 20 degrees .
Due to overlap in colour-magnitude space with Magellanic stars , previously detected tidal features in the old population of Carina are likely weaker than previously thought .
