The Science Performance of JWST as Characterized in Commissioning

This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performance of the spacecraft, telescope, science instruments, and ground system, with an emphasis on differences from pre-launch expectations. Commissioning has made clear that JWST is fully capable of achieving the discoveries for which it was built. Moreover, almost across the board, the science performance of JWST is better than expected; in most cases, JWST will go deeper faster than expected. The telescope and instrument suite have demonstrated the sensitivity, stability, image quality, and spectral range that are necessary to transform our understanding of the cosmos through observations spanning from near-earth asteroids to the most distant galaxies.Comment: 5th version as accepted to PASP; 31 pages, 18 figures; https://iopscience.iop.org/article/10.1088/1538-3873/acb29

spacetelescope/tweakwcs: Maintenance release: Improved compatibility with numpy 2.0. Minor bug fixes and improvements

Algorithms for matching and aligning catalogs and for tweaking the WCS so as to minimize catalog mismatch error

spacetelescope/tweakwcs: Package setup infrastructure reorganization.

<p>Package setup infrastructure reorganization. Python 3.12 compatibility improvements.</p&gt

spacetelescope/tweakwcs: Do not use failed to align images in refcat expansion. Improved 2dhist.

<p>Images that fail to align to the reference catalog when <code>expand_refcat</code> enabled will no longer be added to the reference catalog. [#195]</p> <p>Improved algorithm for initial shift estimation used in catalog matching (<code>2dhist</code>) reduces both memory usage and often processing speed. [#196]</p&gt

spacetelescope/gwcs: GWCS v0.8.0

Changes: LabelMapperRange now returns LabelMapperRange._no_label when the key is not within any range. [#71] LabelMapperDict now returns LabelMapperDict._no_label when the key does not match. [#72] Replaced domain with bounding_box. [#74] Added a LabelMapper model where mapper is an instance of ~astropy.modeling.core.Model. [#78] Evaluating a WCS with bounding box was moved to astropy.modeling. [#86] RegionsSelector now handles the case when a label does not have a corresponding transform and returns RegionsSelector.undefined_transform_value. [#86] GWCS now deals with axes types which are neither celestial nor spectral as "unknown" and creates a transform equivalent to the FITS linear transform. [#92

spacetelescope/gwcs: GWCS v 0.20.0

<p><strong>Changes in GWCS 0.20.0</strong></p> <ul> <li>Replace pkg_resources with importlib.metadata. [#478]</li> <li>Serialize and deserialize pixel_shape with asdf. [#480]</li> </ul&gt
