SGP/EBBR/E7 - Six-Month Checks

During EBBR 6 month checks (formally called 3 month checks) the Automatic 
Exchange Mechanism is disabled (reflected by home signals near zero) so that
the two aspirator units can be placed at the same height.  The measurements
during these periods do not produce correct outputs of bowen ratio (bowen), 
sensible heat flux (h), or latent heat flux (e), nor do the air temperature
and relative humidity measurements indicate correct gradients.  Checks 
performed just before or after the AEM is disabled also lead to some 
incorrect data.  Incorrect 5, 15 minute and half hour data occurs for the 
period above.
