Processing Data From The James Webb Space Telescope

Talkat GOTO Amsterdam 2023 · 2023-06-13..06-15· [data-visualization, web-performance]
slides:none on file

JWST data is freely downloadable from MAST and handled the same way as backyard astro images: control a ZWO/ASI camera with a Raspberry Pi, shoot narrowband frames (some filters as fine as 2.8 nm narrowband), then stack hundreds of exposures with calibration sets (50–100 darks plus flats) — typical raw files ~400 MB each. After optics the target delivers about 20 photons per minute to the sensor, so use high QE detectors, heavy deconvolution and a fast workstation (example: 48 GB RAM disk) to finish processing in tens of minutes.
