ACCESS is a recently approved rocket-borne payload with a ground-based calibration and performance monitoring
program that is designed to transfer the National Institute of Standards and Technology (NIST) absolute
laboratory standards to the stars with a precision and calibration accuracy of 1% across the 0.35-1.7μm bandpass.
This represents a significant improvement in the absolute and relative astrophysical flux calibration system,
particularly at near-infrared (NIR) wavelengths.
Establishing improved spectrophotometric standards is important for a broad range of missions and is relevant
to many astrophysical problems. In particular, the precise calibration of the flux scale across the bandpass
extending from 0.35-1.7 μm is fundamental to the precise determination of dark energy measurements based
on SNeIa photometry.
