[Spice_announce] New WebGeocalc Version 2.5.4

[Boris Semenov]

NAIF is pleased to announce the deployment of the new WebGeocalc (WGC) 
version 2.5.4 (5200 N67 22-NOV-2022) on both NAIF's WGC servers:

      https://wgc.jpl.nasa.gov:8443/ (GUI only)
      https://wgc2.jpl.nasa.gov:8443/ (GUI and Web API)

This new version adds a new Pointing Direction calculation both in WGC 
GUI and in the WGC Web API.

This calculation computes the pointing direction of a user specified 
vector – position, velocity, instrument boresight, instrument FOV 
boundary vector, reference frame axis, or an arbitrary vector – in a 
user specified reference frame and outputs it as a unit or full 
magnitude vector represented in a user specified coordinate system.

For more information about WGC, including tutorials and usage examples,
