Calibration for HST/WFC3, HST/ACS, and HST/STIS

HSTCAL

Calibration software for HST/WFC3, HST/ACS, and HST/STIS.

Nightly regression test results are available only from within the STScI network at this time. https://plwishmaster.stsci.edu:8081/job/RT/job/hstcal/test_results_analyzer/

Install using Conda (Complete Calibration Environment)

HSTCAL can be obtained as part of the Space Telescope Environment (stenv) at https://stenv.readthedocs.io/en/latest/, a conda environment. The instructions found at this URL describe choosing Miniconda or Anaconda (if not already installed), choosing the stenv release, building the stenv environment from the YAML file, and activating your new environment. Once your environment is activated, you can invoke any of the HSTCAL executables.

# Use HSTCAL
$ calacs.e [...]
$ calwf3.e [...]
$ cs[...].e

Install using Conda (HSTCAL only)

The HSTCAL package is resident on conda-forge https://anaconda.org/conda-forge/hstcal, and you can use the following command to perform the installation.

$ conda install -c conda-forge hstcal==X.Y.Z

The X.Y.Z is the desired version number.
