75!     The following factor is the ratio of total O2 band intensity (lines
76!     and Mate continuum) to O2 band intensity (line only).  It is needed
77!     to adjust the optical depths since the k's include only lines.
78Z_O2ADJ = 1.6_JPRB
79
80!     Compute the optical depth by interpolating in ln(pressure),
81!     temperature, and appropriate species.  Below LAYTROP, the water
82!     vapor self-continuum is interpolated (in temperature) separately.
