Jwst

==================

ramp_fitting
------------

- Added documentation for the calculation of the readnoise variance [6924]

--------

- Updated code to allow for drizpars reference file param values to be loaded
when default values in the step are set to `None` [6921]

residual_fringe
---------------

- Fixed the residual fringe code to run on the MIRI MRS LONG detector. [6929]

- Fixed a bug in ``skymatch`` due to which subtracted values were not saved
in the inputs when input was an association table. [6922]

--------------

- Fixed the actual units of the error array used to calculate
photometric errors. [6928]

==================

general
-------

- Update `stpipe` requirement to `>=0.4.1` [6925]

==================

associations
------------

- Add finalization for level 3 group association candidates to require
more than one observation amongst member entries [6886]

datamodels
----------

- Added new MIRI MRS dither pattern "SCAN-CALIBRATION" to list of allowed
values for the "PATTTYPE" keyword. [6908]

- Added MJD unit to keyword comment strings for barycentric and heliocentric
start, mid, and end times. [6910]

extract_1d
----------

- Fix error in variance propagation calculation [6899]

- Set DO_NOT_USE flag in extracted spectrum when the IFU extraction aperture
has no valid data [6909]

pipeline

open an ASN file, and improve the construction of lists of the ASN
members [6855]

- Fixed the logic used in the `calwebb_tso3` pipeline to check for null
photometry results. [6912]

- Check source_ids in `calwebb_spec3` and force into 5 digit positive number,
if available [6915]

- Only apply source_id fix from 6915 to models with multiple
sources [6917]

ramp_fitting
------------

- Fixed multiprocessing error by removing ``int_times`` entirely in step code.
Also, in order to work better with multiprocessing changed the way one group
suppression gets handled and changed the location ZEROFRAME gets handled. [6880]

saturation
----------

- Updated to set the internal threshold for NO_SAT_CHECK and NaN pixels above the
A-to-D limit, so that they never get flagged as saturated. [6901]

--------

- Fixed a couple errors in the step documentation. [6891]

source_catalog
--------------

- Updated the default background box size and minimum number of pixels.
[6911]

tweakreg
--------

- Added check for multiple matches to a single reference source and skip
``tweakreg`` step when this happens. [6896, 6898]

wiimatch
--------

- ``wiimatch`` subpackage has been removed from ``jwst`` in favor of the
external ``wiimatch`` package:
https://github.com/spacetelescope/wiimatch. [#6916]

==================

ami_analyze
-----------

- Fixed the creation of the output product so that it no longer contains
an empty "SCI" extension. [6870]

- Updated the step docs to include information about all of the available
step arguments. [6884]

ami_average
-----------

- Updated the step to handle inputs with different sizes for `fit_image` and
`resid_image`. Larger inputs are trimmed to match the size of the smallest
input. [6870]

associations
------------

- Create level 3 association for background images, and allow background
target observations into level 2 image associations for background
subtraction [6878]

cube_build
----------

- Fixed bug in selecting correct values to extract from the cube pars reference file. [6885]

datamodels
----------

- Updated many reference file schemas to include current
CRDS rmap selectors in schema structure [6866]

documentation
-------------

- Updated the docs for ``calwebb_detector1`` pipeline, as well as the
``linearity``, ``refpix``, ``ramp_fit``, ``saturation``, and ``superbias``
steps to include information on the handling of NIRCam "Frame 0" data.
[6868]

- Update refpix docs to clarify roles of odd_even_rows and odd_even_columns
parameters [6872]

extract_1d
----------

- Catch two more errors raised in the SOSS ATOCA algorithm; one, if an input
ImageModel uses the F277W filter (similar to 6840, which only dealt with
input CubeModels), and another for bad DataModel input type [6877]

- Fix variance propagation for IFU cube extraction in calculations of surface
brightness [6892]

flatfield
---------

- Set DO_NOT_USE DQ bit in flatfield if NO_FLAT_FIELD DQ bit is set in flat
reference file [6882]

pipeline
--------

- Add check to ensure SOSS ``extract_1d`` return is not None, to
avoid photom errors in ``Spec3Pipeline`` and ``Tso3Pipeline``. [6863]

- Updated the ``calwebb_image3`` pipeline to only science members from the
input ASN table. [6875]

ramp_fitting
------------

- Properly handles the returning of ``None`` from ramp fitting for fully
saturated exposures. [6895]

refpix
------

- Add code to refpix step to specify which parameters are used and which are
ignored, depending on data type [6872]

resample
--------

- Speed up the algorithm for computing the sampling wavelengths for the output
WCS in ``resample_spec``. [6860]

set_telescope_pointing

catch spline-fit errors in first order flux estimate [6854]

linearity
---------

- Correct bug when using ZEROFRAME data. [6851]

ramp_fitting
------------

- Remove the logic that only copied the INT_TIMES table content when processing
TSO exposures, so that it shows up in all ``rateints`` products [6852]

- Updated the one good group ramp suppression handler. [spacetelescope/stcal92]

==================

cube_build
----------

- Fix for residual spectral tearing in MIRI MRS multiband cubes [6786]

------------

- Eliminated extra copying of input model when step gets skipped [6841]

----------

- Update keyword comments/titles for V2_REF, V3_REF, FITXOFFS, FITYOFFS [6822]

extract_1d
----------

- Fix bug in SOSS algorithm for bad data by replacing source of possible
infinite values with NaNs, caused by zero division [6836]

- Exit gracefully if data is with F277W filter; avoid masking entire wavemap
if subarray is SUBSTRIP96 [6840]

---

- Update ``test_siafdb`` unit test due to recent SIAF DB update [6842]

linearity
---------
