Descripción
The Dark Energy Survey (DES) will cover some 5000 square degrees in the
southern hemisphere. The survey will use a set of filters which are
derived from the SDSS ugriz set, but are different enough in their
passbands to require new standard stars for use by non-DES observers.
This is especially true for the DES -z and -Y bands.
We present a strategy to develop hydrogen envelope (DA) white dwarfs
stars as potential calibrators for the DES. We will discuss the
observational and modeling effort required to have a set of
well-characterized DAs that span the DES footprint prior to the start of
survey operations. These stars will be used to establish and monitor the
color zero points for the DES photometric system and can be used to
search for systematic errors in the color zero points over the area (ra,
dec) of the survey. These stars will also be used as some of the primary
standards for the DES photometric system which will allow nightly
atmospheric monitoring during DES operations.
