Abstract

Abstract In this paper, we describe the SPHEREx image and spectrophotometry data-processing pipeline, an infrastructure and software system designed to produce calibrated spectral images and photometric measurements for NASA’s SPHEREx mission. SPHEREx is carrying out a series of four all-sky spectrophotometric surveys at 6 . ″ 15 spatial resolution in 102 spectral channels spanning 0.75–5 μ m. The pipeline that will deliver the flux- and wavelength-calibrated data products deriving from these surveys has been developed and is operated by the SPHEREx Science Data Center at Caltech/IPAC in collaboration with the SPHEREx Science Team. Here, we describe the framework and modules used in the pipeline, along with the data products, which are available at the NASA/IPAC Infrared Science Archive.
