Announcements of new observations, pipeline improvements, and CLI / Python client changes.
These packages are in active development — badges track the latest state on GitHub.
The portal and API have moved to campfire-jwst.org / api.campfire-jwst.org. Old campfire.hollisakins.com links will redirect to the new domain, so bookmarks still work.
You will need to sign in again. If you use the Python client/CLI, you will need to reinstall and log in via OAuth again.
The JADES (JWST Advanced Deep Extragalactic Survey) NIRSpec/MSA archive is now available in CAMPFIRE. This adds 5,297 targets and roughly 22,000 spectra across 26 observations in GOODS-S and GOODS-N, spanning the Cycle 1 GTO programs (PIDs 1180, 1181, 1210, 1286, 1287) and the Cycle 2 Origins Field (PID 3215), in PRISM, G140M, G235M, G395M, and G395H.
Explore the data on the spectra browser or the program page, or grab it via the Python client.
cf.iter_objects() and cf.iter_spectra() now follow a server-issued cursor
instead of stepping through numeric offsets. Each page is fetched at a flat
cost, the row count is requested only once, and the walk ends without a
trailing empty request — a full-catalog campfire query objects drops from
tens of seconds to a few. cf.query_objects() / cf.query_spectra() expose
the same mechanism for manual paging through table.meta['pagination'] ['next_cursor'], and the REST endpoints accept it as cursor= (see the
REST reference). offset= keeps working for one
release and is answered with a Deprecation header.
The /api/v1/sync/* endpoints behind campfire sync no longer accept offset
pagination at all: the keyset walk they have used since July is now the only
one, and the extended database timeout that existed for offset clients is
gone. Clients older than 0.5.0 will fail on the second page of a sync with an
upgrade message. Update with git pull && python3 install.py from a repo
checkout, or reinstall from git with pip as described in the
getting-started guide.
The F100LP and F170LP long-pass filters pass light well redward of the nominal G140M and G235M grating cutoffs. The pipeline can now optionally extend the wavelength range of the extraction for G140M/F100LP and G235M/F170LP.
The photometric calibration beyond the nominal cutoff was derived using SPURS (GO#9214) which obtained deep G140M/F100LP, G235M/F170LP, and G395M/F290LP data. A first-pass reduction was done assuming flat calibration in the extended wavelength regime, and line fluxes were measured in each grating. Only emission lines fluxes in the overlapping regions were used for flux calibration to avoid contamination from second-order spectra. The final calibration curve is derived from a smooth polynomial fit and injected into a custom photom reference file. See PR#163 for more details.
The extension is configurable ([nirspec.stage2].extend_g140m_g235m) and is off by default, but has been manually enabled for several programs in the CAMPFIRE database (e.g. SPURS, C3PO).
GO 2565 (PI K. Glazebrook; Cycle 1) is now available — 704 NIRSpec spectra across 7 pointings spanning the COSMOS, EGS, and UDS fields, reduced with the CAMPFIRE pipeline version 0.5.1+d20260609, which corresponds to jwst v1.20.0 and CRDS jwst_1481.pmap. Browse the spectra.
The unified campfire Python package provides an API client and CLI for working
with the archive outside the web portal: query the catalog with coordinate and
metadata filters, pull individual spectra or bulk download the entire database,
and script repeatable workflows.
To install and authenticate with your campfire login, see the getting-started guide.
