Direction-dependent effects

Many of the simulations of direction-dependent effects on the sky make use of the OSKAR simulator. Scripts for these simulations are written specifically for each investigation.

A “cookbook” is provided here to help describe the examples that use OSKAR, and to provide a starting point for writing new scripts.

• OSKAR cookbook
  • Basic concepts
  • Setting up a sky model
  • Setting up a telescope model
  • Defining a parameter space and running simulations
  • Imaging visibility data sets
  • Making an animation

Low-level RFI

These provide scripts to simulate data containing propagated radio frequency interference (RFI) from terrestrial antennas.

  • Propagation attenuation with Pycraf
  • Beam-gain calculation with OSKAR
  • Simulation of visibility with RASCIL
  • Radio Frequency Interference (RFI) interface
