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