JWST Galactic Center survey — arches

2 withheld as bad astrometry. The pipeline repudiated the mosaics these were staged from -- the m2 astrometry checkpoint corrected the offsets table and quarantined every mosaic built before it: F212N. The 88 detector-frame exposures behind those mosaics are withheld with them: the same astrometric solution is baked into the frames. They will return when the field is re-staged from current products.

Detector-frame exposures

The 22 individual exposures (2.4GB) the mosaics above were drizzled from, in the original detector frame, carrying the full distortion solution and this pipeline's astrometry as it stood before the images were resampled onto a sky grid. Each group holds exactly the frames behind the matching mosaic, taken from the record that mosaic itself carries of what went into it. Use these to re-drizzle, re-fit, or chase a per-exposure systematic.

The last detector-frame product differs by field and filter: _crf is the Stage-3 outlier/CR-flagged frame where one was written, otherwise the _destreak / _align / _cal frame the mosaic was drizzled from directly. These are the pipeline's live products rather than frozen copies, so a re-reduction writes a new file beside them and a frame here can become an older generation than the pipeline now holds; they are not covered by CHECKSUMS.sha256. Each file records its own provenance in the keywords below, so a downloaded frame can be identified without reference to this page.

The table ships as a frozen, checksummed copy; the detector frames do not, because a re-reduction rewrites their headers in place. This table, not the FITS, is what makes this version's astrometry reconstructible after the frames have moved on.

2 reference-tie measurement(s) exist for this field, and none is shown here: they are not attached to what this version ships — either the version carries no pointing-correction table, or the measurements postdate the release. A later version's page carries the ties that describe it.
