             abstract = "Reanalyzing Cassini radio observations performed during the 
                         distant flyby of Jupiter in 2000-2001, we study the internal 
                         (rotational) control versus external (solar wind) control of 
                         Jupiters radio emissions, from kilometer to decameter wavelengths, 
                         and the relations between auroral radio components. For that 
                         purpose, we build a database of the occurrence of Jovian auroral 
                         (satellite-independent) radio components bKOM, HOM and DAM 
                         observed by Cassini, and from there we build synthetic 
                         frequencyversus-longitude stacked plots (or maps) of the polarized 
                         intensity of these radio components, that provide signatures of 
                         each radio component. Comparing the stacked plots obtained (i) 
                         along the two legs inbound and outbound of the CassiniJupiter 
                         flyby, and (ii) as a function of the spacecraft longitude or the 
                         Suns longitude, we find that all auroral sources are controlled 
                         internally and externally, HOM \& DAM being dominantly 
                         rotationmodulated (i.e. emitted from searchlight-like sources, 
                         fixed in Jovian longitude), whereas bKOM is dominantly solar wind 
                         modulated (i.e. emitted from strobe-like sources, fixed in Jovian 
                         Local Time). We propose a simple model of internal versus external 
                         control of radio components, and determine ranges for its main 
                         parameters (the amplitude of each control) for HOM \& DAM and for 
                         bKOM. Comparing the inbound Cassini polarized stacked plots with 
                         similar plots built from the 29-years long database of Jupiter 
                         radio emissions observed by the Nan{\c{c}}ay Decameter Array 
                         (Marques et al. 2017), we find that HOM consists primarily of the 
                         low-frequency end of decameter emissions originating from the dusk 
                         more active sector of the Jovian magnetosphere (so-called non-Io-A 
                         and non-Io-C DAM), and is also related to the so-called lesser 
                         arcs identified in Voyager radio measurements, for which there is 
                         no interpretation to date. bKOM consists of a main part above 
                         \∼40 kHz in antiphase with HOM occurrence, and detached 
                         patches below \∼80 kHz (especially intense in the south) in 
                         phase with HOM occurrence.",
