Examples

Generated Sources

Generate three point sources and create the default OSKAR dirty image:

skasim --flux-density 1.0 5.0 10.0 \
  --telescope SKA1MID \
  --observation-time 600 \
  --frequency-mhz 1300 \
  --pixels 1024

Generated source polarization is optional. When supplied, the Stokes Q/U/V lists must match the number of flux-density values:

skasim --flux-density 1.0 5.0 \
  --stokes-q 0.1 0.2 \
  --stokes-u 0.0 0.1 \
  --stokes-v 0.0 -0.1 \
  --observation-time 600

Named-Catalog WSClean Smoke Check

This smoke-check command shape uses the MeerKAT telescope, the named MIGHTEE catalog, the WSClean imager, and an explicit WSClean command:

skasim --telescope MeerKAT \
  --catalog MIGHTEE \
  --imager wsclean \
  --wsclean-command "singularity exec /mnt/software/containers/wsclean-3.10-dysco.sif wsclean" \
  --observation-time 60 \
  --frequency-mhz 1300 \
  --pixels 512 \
  --clean-iterations 100 \
  --output-dir smoke_mightee_wsclean

File-Backed FITS Smoke Check

This smoke-check command shape uses a FITS sky model file and the default OSKAR dirty imager:

skasim --model path/to/sources.fits \
  --telescope SKA1MID \
  --imager oskar-dirty \
  --observation-time 60 \
  --frequency-mhz 1300 \
  --pixels 512
