Region of interest. Different bits of this parameter give a general indication of the region that the spacecraft is in.  The first 18 bits are significant.  An active bit indicates the spacecraft is in a given region.  Multiple bits may be set simultaneously. The value of the bit is in parentheses in the following table.
