# HSTCAL Version 1.3.0

The following updates have been included with this release.

## ACS
- CALACS updates to version 9.2.0 with this release.
- New BLEVCORR algorithm that uses new OSCNTAB, which now correctly calculates bias level for AMP B and D in subarrays.
- New SINKCORR step to apply new SNKCFILE in order to flag sink pixels. See [ACS ISR 2017-01](http://www.stsci.edu/hst/acs/documents/isrs/isr1701.pdf).
- New pixel based PCTECORR algorithm implemented (``CTE_NAME= 'PixelCTE 2017'``).
  * The code defaults to this new algorithm, however, the old one can still be executed using the command line option  ``--ctegen <1|2>``. _Note: The correct accompanying PCTETAB file must also be used._
  * The user can now override the PCTETAB file used (normally specified in the image header) with the command line option ``--pctetab <file path>``.
  * The number of threads used for computing the PCTECORR can now be specified with the command line option ``--nthreads <N>``. _Note: OPENMP is required for N > 1._
- Fixed uninitialized variable in `prinfo.c`.
- Corrected `--version` reporting and added `-r` to report version string that was previously reported by `--version`.

- [x] Affects old data.
- [x] Users should re-retrieve affected datasets from the archive.
- [x] Updated reference files delivered by science team.
