Flux density models of radio calibrators (pwkit.radio_cal_models
)¶
pwkit.radio_cal_models - models of radio calibrator flux densities.
From the command line:
python -m pwkit.radio_cal_models [-f] <source> <freq[mhz]>
python -m pwkit.radio_cal_models [-f] CasA <freq[mhz]> <year>
Print the flux density of the specified calibrator at the specified frequency, in Janskys.
Arguments:
- <source>
the source name (e.g., 3c348)
- <freq>
the observing frequency in MHz (e.g., 1420)
- <year>
is the decimal year of the observation (e.g., 2007.8). Only needed if <source> is CasA.
-f
activates “flux” mode, where a three-item string is printed that can be passed to MIRIAD tasks that accept a model flux and spectral index argument.
