Scientific paper

The flux calibration of the SNAP instruments will be based upon a combination of spectrophotometric standards, including hot white dwarfs and solar analogs, over a wavelength range of 0.35-1.7 microns. To this end, we have been pursuing a project to identify a set of candidate spectrophotometric standards down to V=19, most of which lie in or near the SNAP North field, using the Double Imaging Spectrographs (optical) and the CorMass spectrograph (NIR) on the ARC 3.5m telescope, located at Apache Point Observatory. Since February 2003, we have obtained optical (0.35-0.9 micron) spectra for 20 solar analog and 7 white dwarf candidate standards. We have also obtained NIR (0.8-2.3 micron) spectra for 8 of the 20 solar analog candidates. In this poster, we describe our selection criteria, our observations and reductions, and our results.
We thank the Office of Science at the Department of Energy for support of this research.
