new_pole

Description

Input Files

  • INIT_LITHOS.TXT - Initialization file which contains the parameter PCK, which defines the planetary constants for a variety of objects (such as Bennu or the Sun). This is required for SPICE function calls.

  • DATA/ - Directory containing SPICE kernels.

  • LMRKLIST.TXT - list of landmarks.

/!\ INIT_LITHOS.TXT, DATA/, and LMRKLIST.TXT must be in the working directory.

/!\ unlike pole, new_pole does not require POLE.TXT. Instead the user inputs the pole RA, Dec, PM, OEMGA, via standard input.


Using new_pole

  1. Input the old right ascension (deg), declination (deg), prime meridian (deg), and rate of rotation (deg/day).
