No galaxy left behind: accurate measurements with the faintest objects in the Dark Energy Survey
E. Suchyta, E. M. Huff, J. Aleksić +72
Accurate statistical measurement with large imaging surveys has traditionally required throwing away a sizable fraction of the data. This is because most measurements have have rel…
