See Section 1.4.2 for a basic description of how
QTCM1 determines the values to output. As described in that section,
mean values for output are calculated by the subroutine sump.
This subroutine call for most variables is made shortly after the
variable is calculated; this is true for the major variables (e.g.
, 
, 
).
For a few variables (e.g. STYPE), sump is called
in subroutine varmean, which is described in output.f.
Thus, before outputting mean values of any variable beyond the
standard list given in Table 1.1, you should check both
output.f and qtcm.f (and any other pertinent files) to make sure that
sump has been called (and called only once) for the variable
you wish to output. This is particularly important because for some
of the variables (e.g. dfsu1), sump has been left out or
commented out in the standard release versions of both qtcm.f
and output.f.
