componentlist.sample - Function
1.2.1 Sample the flux of the list in a specified direction. (Not implemented
yet)
Description
The sample function will returns a vector containing the flux in Janskys/pixel
of all the components in the list, in the specified direction, at the specified
frequency. The returned vector always contains four elements corresponding to
the Stokes parameters I,Q,U,V.
