Precession, etc.

Precession correction for J2000 coordinates. Parallactic Angle is the angle of disk rotation as the object traverses the sky. Parallax is the shift of position with the earths position in orbit and diurnal rotation.


Inputs and Outputs for Right Ascension/Declination in either decimal degrees or HH:MM:SS for RA and Deg:MM:SS for Declination now allowed.



This screen has the RA-Dec box checked and the Equatorial inputs/outputs are in Hours/Minutes/Seconds and Degrees/Minutes/Seconds instead of degrees.
