3) Using �aercor and fm, determine the standard ozone and temperature profile used in the
table lookup.
4) Use the EDR external temperature profile to determine the difference between the
actual and standard temperature, �t, for all 11 layers.
5) Use an actual ozone profile to determine the difference between the actual and
standard ozone profile, �x, for all layers for which there is an actual retrieval.

Calculate dxerr (error in ozone profile shape correction) and dterr (error in
temperature shape correction (to be used in weighted average to obtain final
ozone amount)
Subroutines called by tpcor:
prfind: determines profile index (the pointer that indexes the correct profile in the table);
qvalue: determines table values
qvprof: calculates q values. It calls the following subroutines:
intlyrn: computes q values for selected lambda using the dn/dt table for the Northern
Hemisphere.
Intsou: computes q values for selected lambda using the dn/dt table for the Southern
Hemisphere.
