Function polarDistanceRadians( ra1, dec1, radius1, ra2, dec2, radius2 )
- Description:
-
Calculates the distance in three dimensional space
between two points specified in spherical polar coordinates.
- Parameters:
-
ra1
(floating point)
- right ascension of point 1 in radians
dec1
(floating point)
- declination of point1 in radians
radius1
(floating point)
- distance from origin of point1
ra2
(floating point)
- right ascension of point 2 in radians
dec2
(floating point)
- declination of point2 in radians
radius2
(floating point)
- distance from origin of point2
- Return Value (floating point):
- the linear distance between point1 and point2;
units are as for
radius1
and radius2
- Signature:
double polarDistanceRadians(double, double, double, double, double, double)
