Public Member Functions | |
| Position () | |
| Default constructor: calls default constructor of Vector. | |
| Position (Vector vec) | |
| Position (double theta_inp, double phi_inp) | |
| Identical to the Vector constructor with the same inputs. | |
| Position (double longitude, double latitude, double altitude) | |
| double | Lat () const |
| Returns latitude, where the +z direction is at 0 latitude. | |
| double | Lon () const |
| Returns longitude. More... | |
| double | Distance (const Position &second) const |
| Returns chord distance (direct distance between two vectors) | |
| double | SurfaceDistance (const Position &second, double local_surface) const |
| Returns "surface distance" between two positions. More... | |

Definition at line 26 of file position.hh.
| Position::Position | ( | double | longitude, |
| double | latitude, | ||
| double | altitude | ||
| ) |
Constructs a position vector given a longitude, latitude, and distance from the center of the Earth.
Definition at line 17 of file position.cc.
| double Position::Lon | ( | ) | const |
Returns longitude.
where 0 degrees longitude corresponds to phi = 270 deg (-y axis), and increases clockwise. Hence, lon=0 -> phi=270, lon=90 -> phi=180, lon=180 -> phi=90, lon=270 -> phi=0,
Definition at line 51 of file position.cc.
| double Position::SurfaceDistance | ( | const Position & | second, |
| double | local_surface | ||
| ) | const |
Returns "surface distance" between two positions.
The surface distance is the the length of arc between two positions. Altitude (i.e. length of the position vector) is irrelevant; only angle between the two position vectors is considered.
