Updated line parameters, including line positions and intensities, have been generated for the six strongest A(2)Sigma(+)(v') - X(2)Pi(i)(v") bands of OH, i.e., v' - v" = 0, + 1, v" = 0, 1, 2, applicable to atmospheric and high temperatures. Results from recent laboratory measurements and theoretical studies have been incorporated into the calculations. Tables of line parameters are available for 296 and 4600 K.
