C> @brief Read master Table B information from local file system
 
C> This subroutine reads master Table B information from two separate
C> ASCII files (one standard and one local) and then merges the
C> output into a single set of arrays.
C>
C> <p>Each of the two ASCII files must already be individually sorted
C> in ascending order with respect to the FXY numbers.
