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 Astroconda Pipeline Builds at https://astroconda.readthedocs.io/en/latest/releases.html.
The simplest way to get the most recent environment would be:

1. Install Miniconda or Anaconda (if not already installed) using the instructions at https://astroconda.readthedocs.io/en/latest/getting_started.html.

2. Create a conda environment with the HSTCAL included:

# Add the AstroConda channel to ~/.condarc
$ conda channel --add http://ssb.stsci.edu/astroconda

# Create a dedicated calibration environment
$ conda create -n calib python=3 stsci-hst

# Activate the environment
$ source activate calib

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

Install using Conda (HSTCAL only)

To install only HSTCAL into an existing enviroment, you need to provide the exact version desired, as conda install hstcal will not install the latest version due to a known resolver issue.

$ conda install hstcal==X.Y.Z -c http://ssb.stsci.edu/astroconda

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