Step -1.2: PRISim Validation

[steven-murray]

This should be a formal test of PRISim. It should be based heavily on the tests done here: RadioAstronomySoftwareGroup/pyuvsim#211, but made into a formal validation test.

• Simulation Component: GSM, GLEAM
• Simulators: PRISim, pyuvsim
• Pipeline Components: None
• Depends on: Ideally, will depend on the automatic -1 notebook being worked on by @piyanatk.

Why this test is required

PRISim is currently not being used for many validation tests, but it will be very useful when validating against 21cm simulations (eg. from 21cmFAST), as it has built-in support for this.
Thus it should be validated in the same way as all the simulators.

Summary

A brief step-by-step description of the proposed test follows:

• Construct visibilities from increasing-complexity sky models, both with PRISim and pyuvsim.
• Compare visibilities explicitly, and report on the level of absolute and relative error between simulators, especially as a function of frequency.

Simulation Details

• Freq. range:
• Channel width:
• Baseline/antenna configuration:
• Total integration time:
• Number of realisations:

Criteria for Success

• Visibilities match to 1% between simulators across all frequencies, baselines and LSTs.
