0.13.2 (2019-05-14)

assign_wcs

• The MIRI LRS WCS was updated to include an nverse transform. [#3106, #3360]
• The MIRI LRS spectral distortion is implemented now using a spline model. [#3106]
• Both dither_point_index and metadata_id are used now to match rows into the MSA meta file. [#3448]
• MissingMSAFileError was renamed to MSAFileError [#3448]
• Added two parameters to assign_wcs, slit_y_low and slit_y_high, to allow changing the lower and upper limit of a Nirspec slit in the instrument model. [#2819]

background

• Verify the exposures to be used as background have the same NIRSpec GWA tilt values as the science exposures. If the background and science exposures do not have matching GWA tilt values, then skip the background subtraction step in calspec2. [#3252]

barshadow

• Updated to apply the correction to the science data arrays, in addition to attaching as an extension. [#3319]
• Updated to apply the square of the correction to VAR_FLAT [#3427]

calwebb_spec3

• Add the master_background subtraction step to the pipeline. [#3296]

combine_1d

• Fix call to wcs.invert, and don't weight flux by sensitivity if the net column is all zeros. [#3274]
• Modified to use the same columns as now written by extract_1d. The background parameter has been removed, since dividing by npixels is now done in extract_1d. [#3412]

datamodels

• Fix url_mapper for fits-schema to allow URLs with of the format http://stsci.edu/schemas/fits-schema/ to map to the correct location in the jwst package. [#3239]

extract_1d

• This step can now use a reference image for IFU data. The reference image (for IFU) may be either 2-D or 3-D. When using a reference image for non-IFU data, background smoothing is now done after scaling the background count rate. [#3258]
• Unit tests were added for IFU data. [#3285]
• The target coordinates are used (for some modes) to determine the extraction location, i.e. correcting for nod/dither offset. For IFU, the areas of the source aperture and background annulus are computed differently. [#3362
• For IFU data for an extended source, the extraction parameters are assigned values so that the entire image will be extracted, with no background subtraction. For non-IFU data, a try/except block was added to check for a WCS that does not have an inverse. Some code (but not all) for the now-obsolete RELSENS extension has been deleted. [#3390]
• This now writes columns SURF_BRIGHT and SB_ERROR instead of NET and NERROR. The BACKGROUND column is divided by NPIXELS, so the units will be surface brightness. This step no longer looks for a RELSENS extension. [#3412]
• The keywords that describe the units for the FLUX and ERROR columns have been corrected; the units are now specified as "Jy". [#3447]

extract_2d

• An attribute dither_point was added to each slit in a MultiSlitModel for MOS observations. [#3448]

flatfield

• Propagate uncertainty from flat field into science ERR array and new VAR_FLAT array which holds the variance due to the flat field. [#3384]

master_background

• Modified the unit tests for expand_to_2d. [#3242]
• Modified MasterBackgroundStep to be skipped if BackgroundStep was already run on the data. A new force_subtract parameter is added to override this logic. [#3263]

• Updated the DQFlags of the background subtracted data to be DO_NOT_USE for the pixels that have wavelengths outside the master background [#3326]
• Modified expand_to_2d to loop over pixels for WFSS data. [#3408]

set_telescope_pointing

• Fix populate_model_from_siaf to convert SIAF pixel scale from arcsec to degrees for CDELTn keywords. [#3248]
• Updates to prevent crashes when SIAF values needed for crpix or cdelt keywords are missing. [#3316]

• Fixed a bug in handling situations when no useable sources are detected in any of the input images. [#3286]
• Enhanced source catalog extraction algorithm to filter out sources outside the WCS domain of definition (when available). [#3292]
• Changed the type of exception raised when input has incorrect type. [#3297]

0.13.1 (2019-03-07)

combine_1d

• Added parameter background; for background data, scale the flux, error, and net by 1 / NPIXELS, and include NPIXELS in the weight; changed the default for exptime_key to "exposure_time". [#3180]
• There is now a direct interface for calling the step. This function, combine_1d_spectra, may be passed either a ModelContainer or a MultiSpecModel object. Previously this function expected the name of an association file. [#3220]

datamodels

• Add back BaseExtension class so url-to-schema mapping works again [#3227]

extract_1d

• If flux conversion is done, the FLUX is now set to zero (instead of copying the NET) if the wavelength of a pixel is outside the range of the RELSENS array. [#3190]
• Added a parameter subtract_background to extract_1d indicating whether the local background should be subtracted. If None, the value in the extract_1d reference file is used. [#3157, #3186]
• extract_1d can be run by calling extract.do_extract1d and passing a dictionary of reference file information. [#3202]
• ref_dict was None in run_extract1d, and a check for that was missing. [#3233]

master_background

• Added unit tests for expand_to_2d. Support CombinedSpecModel data for the 1-D user-supplied background spectrum. [#3188]

set_bary_helio_times

• Raise an exception when unable to compute converted times. [#3197]

set_telescope_pointing

• Added population of CDELTn keywords based on SIAF values and fixed bug in calculation of S_REGION corners. [#3184]
