[TRNSYS-users] Type 1288 solar library (TESS)

[Jeff Thornton via TRNSYS-users]

The format of the incidence angle modifier data file is similar to any
of the other models that use the bi-axial format: 

The first line in the data file must include the transverse angles for
which data is provided - in ascending order - and from 0 to 90 degrees. 

The second line in the data file must include the longitudinal angles
for which data is provided - in ascending order - and from 0 to 90
degrees. 

The next N lines contain the value of the incidence angle modifier at
the combination of the longitudinal and transverse angles, where N is
the number of longitudinal angles (NL) multiplied by the number of
transverse angles (NT). These values repeat for NL times for a given
transverse angle. 

A few things to remember: 

Make sure to set the correct parameter values based on the number of
angles that you have 

The text file must be pure ASCII text 

The data interpolation routine will not extrapolate beyond the bounds of
your data - so make sure you have the extremes covered 

An example helps illustrate the format 

0 10 20 30 40 50 60 70 80 90 !Transverse angles
0 15 30 45 60 75 90 !Longitudinal angles
1.0000 !IAM at T=0,L=0
0.9000 !IAM at T=0,L=15
0.8000 !IAM at T=0,L=30
0.7000 !IAM at T=0,L=45
0.6000 !IAM at T=0,L=60
0.5000 !IAM at T=0,L=75
0.4000 !IAM at T=0,L=90
