HSTCAL Version 2.2.0rc2

The following updates, specified in separate sections for each instrument, have been included with this release. This release is presented as HSTDP-2018.3 milestones

HSTCAL package updates

  • Regression testing has been implemented via pytest and Jenkins.
  • The CFITSIO library is no longer built as a static library incorporated into the HSTCAL executables.

HSTIO

HSTDP-2018.3 Milestones

  • HSTIO updates to Version 2.7.
  • Functionality has been added to determine the number of HST IMSETS in a FITS file in a robust fashion PR#330.

ACS

HSTDP-2018.3 Milestones, Data Changes

  • CALACS updates to Version 10.1.0 due to updates in the ACSCCD and ACS2D algorithms.

  • The dark correction, DARKCORR step of the ACS2D algorithm, has been modified to work directly on the full 2D data rather than on a line-by-line basis PR#315.

  • The bias shift correction, BLEVCORR step of the ACSCCD algorithm, has been upgraded to accommodate the new supported subarrays which have both physical and virtual overscan PR#312. This is the same algorithm which applies to full frame data.

  • Forward model functionality was implemented which exploits the existing CTE code and usage (Generation 2 only). Instead of correcting the CTE trails, the forward model functionality simulates (adds) the trails PR#313. This functionality should be accessed via the new ACSTOOLS function, acscteforwardmodel.py

  • Updated ACS library routine, getacskeys, updated to call the new HSTIO function which robustly determines the number of IMSETS in a FITS file PR#330.

STIS

    • #366 - Fix out of bounds memory access: changes data.
    • #93 - Remove unessacary re-computation of cte correction due to over-subtracted tails: no change to data.
  • Code tidy up to CTE correction inwf3cte.e

    • #367 - Remove unnecessary critical section.
  • Affects old data

HSTCAL Version 2.2.0rc1

This is a tagged version of HSTCAL, but it was never actually released to DMS.

This release is an immediate update and counterpart to the HSTCAL 2.1.0 release which predominantly addressed ACS enhancements, supplemented by changes to WFC3 and HSTIO. This release contains only changes for WFC3. The HSTCAL Minor version designation has been increased as the CTE corrected data exhibits a change from previous output.

WFC3

  • CALWF3 bumped to Version 3.5.0 for this release.
  • Bug fixes to CTE correction inwf3cte.e

HSTCAL Version 2.0.0

The following updates, specified in separate sections for each instrument, have been included with this release. This release is presented as HSTDP-2018.1 milestones.

HSTCAL package updates

  • The separate trailer file support routines used by ACS, WFC3, and STIS were consolidated into a single file, and are now part of libhstcallib.a.

HSTIO

HSTDP-2018.1 Milestones

  • Improvements in robustness and maintainability have been made to the infrastructure software (HSTIO) and libraries which are the foundation for the pipelines.

ACS

HSTDP-2018.1 Milestones, Data Changes

  • CALACS updates to Version 10.0.0 due to the modifications imposed by the upgraded ACSREJ algorithm.

  • An updated ACSREJ algorithm was implemented where all calculations are now done in electrons versus DN. The threshold computation uses the ERR arrays to account for post-flash noise PR#2.

  • CALACS now uses the amp-dependent read noise as the threshold to determine if a pixel has enough signal-to-noise ratio such that a reasonable correction can be applied PR#258.

  • A bug fix has been implemented which is only applicable for RAWs with PCTECORR=PERFORM for ASNs used for cosmic ray rejection. In this case the CR rejected output (CRJ) previously used the wrong dark; it used the CTE-corrected dark. This has been addressed, and the CRJ product is now correct utilizing the non-CTE corrected dark PR#273.

  • All BIAS files are now processed by CALACS to use only read noise (vs Poisson) for the computation of the ERR array as the date discriminant (pre- and post-SM4) has been removed PR#288.

  • The C interface to the ACSREJ standalone component of CALACS was modified for clarity. The "newbias" option was renamed "readnoise_only". The functionality associated with this option remains the same.
