Featured Data Products
JWST data will be available in various stages:
- Raw FITS Files (Stage 0): Raw spacecraft output converted to FITS file format
- Detector Corrected Exposures (Stage 1): Output count-rate images after applied detector-level corrections to raw data
- Flux Calibrated Exposures (Stage 2): Fully-calibrated individual exposures, and associated files, to all imaging/spectroscopy data and modes
- Calibrated Combined Products + Associations (Stage 3): Combined final data products specific to each observing mode
