resolve

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.

Installation

• Install nifty7, ducc0, matplotlib, scipy (see Dockerfile)
• Optional dependencies are:
  • For reading measurement sets, install python-casacore.
  • For reading and writing FITS files: astropy.
