ab5.dc contains daylight coeffs with fin;
ab5nofin.dc contains daylight coefficients with no fin.

These are with 5 bounces

To run, copy to mz350.dc

Also change insolation distribution so that direct goes only to floor, 
otherwise some is lost back out of room. This has not been a 
problem in other models because insolation analysis was done 
to allocate direct solar. However, in daylight coeff method, 
there are no shading/insolation files (although it should be 
possible to include insolation analysis in principle if daylight 
coeffs are only used for external surfaces.

For results submitted, use the mz350c files with ab5nofin.dc 
as the results for the unshaded case (mz340) and the results 
with ab5.dc for the results with the shading fin. This is
necessary as the daylight coeff method gives approx 2% less annual
solar. Since most of the important results are mz340 - mz350, 
it is necessary to use the same method for both.
