componentlist.setfreqframe - Function
1.2.1 Set the reference frame for the frequency
Description
The setfreqframe function sets the reference frame for the reference frequency
of the specified components.
Currently the reference frame does not include additional information like when are where the observation took place. Hence no conversion between reference frames is available. In the interim I recommend you always use the same frame.
