You are mixing terms. In this filing, the term beam was used for both beam and coverage maps but they put a L or R marker at the end of the beam name when identifying a beam "map". A beam "map" may be served by any number of transponders and polarities, depending on design, ie; a conus satellite with all transponders on one beam "map".
So, for Puerto Rico, there is only one beam "map", B23RL, which shows the coverage area and contours for whatever transponders and polarities are associated with coverage of that area.
OK, so if I'm understanding this correctly even though there will actually be two physical overlapping spotbeams beams carrying even and odd channel sets covering Puerto Rico, only one beam "B23" is used to represent both on the coverage map since the two are identical?
