The expected lower-level SPHEREx data products will be available to the community via IRSA and are:
Calibrated Spectral images: Available within two months of acquisition, these linear variable filter (LVF) images will be photometrically and astrometrically calibrated and are ready for science analysis, including photometric measurements.
All-sky Data Cubes: Produced after the first and second years of the survey, these all-sky maps will contain 102 spectral channels.
High Reliability Source Catalog: Produced after the third survey, and again at the conclusion of the primary mission, this catalog will contain time-resolved calibrated spectra for high SNR stars and galaxies.
