| Abstract: |
The Dark Energy Survey (DES) is an optical (grizY) program which is currently
imaging 5000 sq. deg. in the southern galactic cap. An internal relative calibration
scheme has been devised to tie the survey uniformly. However, coupling the DES to an
external standard in order to ultimately set the filter zeropoints to a known flux
scale will make use of DA white dwarfs. We describe the WD characterization program
and present a current status of the effort. |
