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 is a single row file that 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.

POLE.TXT Example

       86         -65      89.00000000    2010.48945

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)

determine whether you want the rotation rate fixed ( y for yes, n for no)
0 if you want to iterate, 1 if you want to keep result (updates POLE.TXT), 2 if you want previous result (nominal if on 1st iteration)
