Description
Block Besselian Epoch to Julian Epoch converts the values of the components of the radius vector and speed assigned to the epoch B1950.0, in the corresponding values and assigned to the J2000.0 epoch by the formula:
where
Ports
Entrance
rB1950 is the radius vector assigned to the epoch B1950.0
3-by-1 vector
The coordinates of the radius vector, assigned to the epoch B1950.0.
