Drizzlepac is a set of software tools maintained by the Space Telescope Science Institute (STScI) that is designed to align and combine astronomical images obtained with the Hubble Space Telescope. Drizzlepac includes core features such as AstroDrizzle, Tweakreg, and the Hubble Archival Program (HAP) data processing pipeline that creates Single-Visit and Multi-Visit Mosaics (SVMs and MVMs).
Nightly regression test results are available at spacetelescope/RegressionTests.
The use of this software on HST data is described at: https://drizzlepac.stsci.edu/
A complete description of the documented interfaces in the code itself can be found at: https://drizzlepac.readthedocs.io
Drizzlepac is installed when you install the stenv conda environment (a replacement for astroconda). Select your desired release and follow the instructions on the stenv installation page.
$ pip install git+https://github.com/spacetelescope/drizzlepac.gitThe option --no-use-pep517 MAY be required in order to correctly build
the C extensions with pip versions up to 22.2, after commenting out
the build-backend from the pyproject.toml config file.
Support for installing using pip is still evolving, so use of this
command is provided on an experimental basis for now.
$ git clone https://github.com/spacetelescope/drizzlepac
$ cd drizzlepac$ pip install .Note: If you intend to use drizzlepac's embedded help feature from within
an interactive python or ipython session, we recommend you do not skip
this step.
