Re: theta_fo documentation mismatch

[ansley@xxxxxxxxxxxxx (Ansley Manke)]

Ferret users:

Clarification on my earlier mail.  The arguments to THETA_FO are 

THETA_FO( salt, temp, Z, Z_reference )

Where Z should refer to Pressure and Z_reference to reference pressure  (I'd said
								temperature)


The Users Guide will be changed to call these P rather than Z
