LoSiTo

The LOFAR simulation tool

LoSiTo is a Python package that can be used to produce simulated LOFAR visibilities with a variety of corruptions and effects.

It includes:

• Time- and direction-dependent ionospheric effects (TEC and rotation measure)
• Beam effects
• Station-based delay effects (clock and polarization misalignment)
• Realistic noise

Furthermore, LoSiTo features the simulation of LOFAR2.0 simultaneous LBA-HBA observations.

The full documentation can be found at the LoSiTo webpage.

Software requirements:

• casacore and python-casacore
• DP3
• LoSoTo
• RMextract
• LSMTool
• Python 3.6+ (including scipy, numpy, and astropy)
