pole
Description
The program pole solves pole right ascension, declination, and rotation rate for a body in principal axis rotation. The rotation rate is calculated in degrees/day while right ascension and declination are in degrees.
For pole to run, POLE.TXT and LMRKLIST.TXT are required in the working directory. LMRKLIST.TXT is just a file containing a list of landmarks and POLE.TXT contains the predicted pole RA (deg), DEC (deg), PM (deg), and OMEGA (deg/day). These values are given in the .tpc kernel file for the object.
Input-Files
POLE.TXT - simple text file containing nominal pole RA (deg), DEC (deg), PM (deg), OMEGA (deg/day)
[LMRKLIST.TXT - list of landmarks
Input stdin
- A time in UTC (make sure it is within the span supported by the kernels)
