SGP/EBBR/E9 - Reprocess: Soil Heat Flow #4 Incorrect

Soil Heat Flow #4 was incorrect during these periods as a 
consequence of the repair of Soil Temperature #5.  
See below for a work-around.

Recalculate the average soil heat flow (ave_shf),
latent heat flux (e), and sensible heat flux (h) 
using only soil sets 1, 2, 3, and 5, as follows:

ave_shf = (g1 + g2 + g3 + g5)/4

e = -(q + ave_shf)/(1 + Bowen)

h = -(q + e + ave_shf)

where q is net radiation and Bowen is the Bowen ratio.

• Surface latent heat flux(latent_heat_flux)
• Surface soil heat flux, average of fluxes 1-5(surface_soil_heat_flux_avg)
• Soil heat flow 4, corrected for soil moisture(corr_soil_heat_flow_4)
• Soil heat flow 4(soil_heat_flow_4)
• Surface soil heat flux 4(surface_soil_heat_flux_4)
• Surface sensible heat flux(sensible_heat_flux)
