This document briefly describes two C-curve flagging routines for TES level
2 Ozone products.  The logic of these routines and the reasons for using
them are described in the TES Data Users Guide, section 5.1.1.2.


1) SUMMARIES OF EACH ROUTINE AND ITS USAGE


----
FUNCTION ccurve_test
----

This routine offers the same logic as found in the TES CcurveQA flag found in
version V004 data for users working on V003 data.  It accepts individual
profiles and returns a flag (0 for no c-curve found, 1 for c-curve found).

The basic calling syntax is:

flag = ccurve_test(TES_pressure_profile,
		   O3_initial,
		   O3_retrieved)

See the program header for details.



----
FUNCTION get_tes_outlier
----

This routine provides the c-curve screening developed by Lin Zhang. This 
function accepts arrays of profiles (67xN, where 67 is the TES pressure
levels and N is the number of scenes.

The basic calling syntax is:

flag_array = get_tes_outlier(TES_pressures,
			     O3_retrieved_array,
			     O3_initial_array,
			     AK_diagonal_array)

See the program headers for details.
