JWST Build 8.0

Release notes

Association generator software and rules have been updated to:

  • fix unnecessarily large memory footprint for large pools
  • prevent level 2 and 3 associations for NIRCam TSGRISM exposures on the NRCBLONG (NRCB5) detector
  • add valid optical paths for NRS_LAMP exposures, in order to generate or exclude associations for specific lamp, disperser, and detector combinations

Updates to the Level-1b set_telescope_pointing script to:

  • add the "fgsid" option

Updates to Level-2a processing for all exposure modes include:

  • enable the use of NIRCam "frame zero" data to estimate slopes for pixels that are saturated in all groups
  • reduce memory usage in the dark_current step and improved memory performance of the entire pipeline
  • bug fix in "ramp_fitting" for handling CR hits that occur in the first good group after flagged first frames
  • fixed the handling of segmented data products in the MIRI "reset" step
  • updated the "saturation" step to flag neighbors of saturated pixels, to account for charge spilling

*Updates to Level-2b imaging (calwebb_image2) processing include:

  • corrections to the computation of the CRPIXn keyword values
  • fixes to the parsing of the FILTEROFFSET reference file used in the "assign_wcs" step

Updates to Level-2b spectroscopic (calwebb_spec2) processing include:

  • a fix for spectral tearing in MIRI MRS IFU cubes
  • the implementation of the IDT-supplied algorithm for NIRISS SOSS 1-D spectral extraction
  • addition of the "background" step parameter "wfss_mmag_extract", which is used to limit the list of sources used in the computations
  • updated the IFU "cube_build" step to use "drizzle" weighting by default, rather than "EMSM"

Updates to the Level-3 imaging (calwebb_image3) processing include:

  • changes to some of the default parameter values for the "tweakreg" step, to eliminate errors encountered for some commissioning observations

Updates to the Level-3 spectroscopic (calwebb_spec3) processing include:

  • the implementation of the IDT-supplied algorithm for NIRISS SOSS 1-D spectral extraction
