Our story begins under the following hypothetical: one has just acquired ALMA data on a Fermi source. Not just any Fermi source but the famous source `3C273`_, the first quasar ever to be identified. This radio-loud quasar was also very recently detected by Fermi as 2FGL J1229.1+0202, and has already has a large amount of multi-wavelength data. How do these new data (Fermi, ALMA) augment the extant SED and what physical knowledge can be deduced by their incorporation?
