|
values using the Perez all-weather model. |

by DAYSIM, which contains a short header with the site parameters followed |
| 47 |
|
by the month, day, standard time, direct normal and diffuse horizontal |
| 48 |
|
irradiance values, one time step per line. |

Alternatively, a standard EPW (Energy Plus Weather) input may be provided, |
| 50 |
+ |
in which case additional information such as the dew point temperature may |
| 51 |
+ |
be used in the calculation. |
| 52 |
|
Each time step line is used to compute a column in the output matrix, |
| 53 |
|
where rows correspond to sky patch positions, starting with 0 for |
| 54 |
|
the ground and continuing to 145 for the zenith using the default |
