Multiple studies demonstrate that extracting infrared data from early astronomical sources using the James Webb Space Telescope requires the standard JWST calibration pipeline paired with specialized custom filtering and calibration techniques.
The retrieved papers extensively document the data reduction methodologies for JWST instruments (NIRCam and MIRI) across major surveys like CEERS, GLASS-JWST, and COSMOS-Web. Every single relevant methodological paper confirms that processing infrared observations from early sources relies on the official JWST Calibration Pipeline augmented by specialized custom filtering, background subtraction, noise removal, and calibration steps. Therefore, the claim is fully supported by the evidence.
