The |
| 58 |

.I \-A |
| 59 |
+ |
option tells |
| 60 |
+ |
.I gendaymtx |
| 61 |
+ |
to generate a single column corresponding to an average sky |
| 62 |

computed over all the input time steps, rather than one |
| 63 |

column per time step. |

The |
| 66 |
|
.I \-c |
| 67 |

option may be used to specify a color for the sky. |
| 68 |
< |
The gray value should equal 1 for proper energy balance |
| 68 |
> |
The gray value should equal 1 for proper energy balance. |
| 69 |

The default sky color is |
| 70 |
|
.I "\-c 0.960 1.004 1.118". |

The |
| 79 |
|
.I \-d |
| 80 |
< |
option may be used to produce a sun-only matrix, with no sky contributions. |

and the ground patch also set to zero. |
| 82 |

Alternatively, the |

|
.I \-s |
| 84 |

option may be used to exclude any direct solar component from the output. |

By default, |
| 92 |
|
.I gendaymtx |
| 119 |
|
.I \-O1 |
| 120 |
|
option specifies that output should be total solar radiance rather |
| 121 |
|
than visible radiance. |
| 122 |

The |
| 123 |
+ |
.I \-h |
| 124 |

option prevents the output of the usual header information. |
| 125 |
|
Finally, the |
| 126 |
|
.I \-v |
| 127 |
|
option will enable verbose reporting, which is mostly useful for |
| 143 |
|
based on Jean-Jacques Delaunay's original gendaylit(1) implementation. |
