8.3.4.2 Flux and Temperature Unit Conversion

To convert measurements in Kelvin to Jansky (and vice versa), the convert_flux function may be used. This converts and scales the data to the selected units. The user may need to supply the aperture efficiency, telescope diameter, or the Jy/K factor

  scans.convert_flux(eta=0.48, d=35.) # Unknown telescope
  scans.convert_flux(jypk=15) # Unknown telescope (alternative)
  scans.convert_flux() # known telescope (mostly AT telescopes)
  scans.convert_flux(eta=0.48) # if telescope diameter known
