  • The first column gives the coordinates of the pairings, according to the gapped sequence alignment (see materials and methods). The second column gives the stem length (in base pairs). Columns 3 and 4 give values of × and the LRT statistic (Muse 1995) for each pairing. The numbers in columns 5 and 6 represent the number of Watson-Crick (WC) and wobble (WOB) covariations observed for each pairing region, with the number of internal covariations given in parentheses.
