Hello Henk and All LamIII is the Central Meridian Longitude System III. This is the name you see in the wonderful Radio-Jupiter Pro 3 RJP3 software created by Jim Sky, that we use in our daily work. Io it the Io phase angle, the angle along its orbital plane measured from superior conjunction, as seen from Jupiter's center, named Io Phase in RJP3. SubIo is the CML (System III) of the direction to Io, as seen from Jupiter's center. Storm is the type of Jupiter Radio Map region: A is non-Io-A B is non-Io-B C is non-Io-C Io-A is the Io-A region in RJP3 Io-B is the Io-B region in RJP3 Io-C is the Io-C region in RJP3 Io-D is not predicted in the UFRO tables. Please see: http://herrero-radio-astronomy.blogspot.com/2011/08/io-d-predictions-with-radio-jupiter-pro.html for RJP3 predictions. Fla is the Jovian hour angle from Florida (UFRO). Calif is the Jovian hour angle from California (Owens Valley RO). Prob18 is the radiation probability based on 18 MHz Yagi 1985-92 observations from UFRO. Prob26 is he radiation probability based on 26 MHZ Dipole Array 1973-81 observations From UFRO. My ignorance is vast, please correct my mistakes. Many thanks.
