Resolve aims to be a general radio aperature synthesis algorithm. It is based
on Bayesian principles and formulated in the language of information field
theory. Its features include single-frequency imaging with either only a
diffuse or a diffuse+point-like sky model as prior, single-channel antenna-based
calibration with a regularization in temporal domain and w-stacking.
Resolve is in beta stage: You are more than welcome to test it and help to make
it applicable. In the likely case that you encounter bugs, please contact me
via email.
Requirements
For running the installation script:
Python version 3.10 or later.
C++17 capable compiler, e.g. g++ 7 or later.
pybind11>=2.6
setuptools
Automatically installed by installation script:
ducc0
nifty8
numpy
Optional dependencies:
astropy
pytest, pytest-cov (for testing)
mpi4py
python-casacore (for reading measurement sets)
h5py
matplotlib
dask-ms[xarray, zarr] (for reading pfb-clean xds files)

Installation
For a blueprint how to install resolve, you may look at the Dockerfile.
For installing resolve on a Linux machine, the following steps are necessary.
First install the necessary dependencies, for example via:
pip3 install --upgrade pybind11 setuptools
Finally, clone the resolve repository and install resolve on your system:
git clone --recursive https://gitlab.mpcdf.mpg.de/ift/resolve
cd resolve
pip install --user .
