Parameters
| Name | Type | Description |
|---|---|---|
| _ptg | tatukgis.pdk.TGIS_Point | observer's location in geographic coordinate system expressed in radians |
| _local_time | TDateTime | observer's local time |
| _utc_offset | float | time difference in hours between UTC and local time for a particular place and date; Daylight Saving Time must be taken into account. |
| _altitude | float | angular height in radians of the sun in the sky measured from the horizontal; values from 0 at sunrise and sunset to 90 at solar noon (also known as an elevation angle) |
