Release Notes

Highlights

The Level-1b script "set_telescope_pointing" has been updated to insert moving target coordinate keywords into level-1b product headers when the coordinate data is available in a moving target position table extension provided by SDP.

Association generator rules have been updated to:

  • Limit NIRSpec IFU level 3 associations to contain data from a single grating+filter combination
  • Produce level 2b and 3 associations for nodded observations for all spectroscopic modes
  • Exclude dark exposures from all associations

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

  • Significant reduction in the memory footprint for processing of all exposure types

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

  • Populate ASNPOOL and ASNTABLE keywords for all products using an ASN to drive processing

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

  • Bug fixes and refactoring of WCS transforms for WFSS exposures

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

  • Only load science and background members from an input ASN file
  • The new capability to align image WCS to the Gaia catalog
  • Added new capability to align moving target exposures in the moving target coordinate frame
  • Source catalog generation has been completely rewritten to include new types of source measurements
  • Updates to several steps to make them more robust to garbage data
  • Many bug fixes to the creation of combined/resampled NIRSpec and MIRI LRS spectra

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

  • Update level-2b source-based products to include metadata from input exposures
  • 1-D extracted products for WFSS mode now contain all data for a given source in a single x1d product
  • Combined 1-D products for WFSS mode use the new product type suffix "c1d"
  • Updated mrs_imatch to make it more robust to data that is out of specification

Updates to the Level-3 WFS&C (calwebb_wfs-image3) pipeline include:

  • Updated the ASNTABLE keyword in all combined (wfscmb) image products
