Glish Client for Computing Positions of Planets, Pulsar Pulse Delays, LST, Precession, Nutation and Aberration Table of Contents object track object doppler doppler fraction ... barycentric object XYZ coordinates Introduction This document briefly desribes the events recognized by the glish "solar_system" client program. This client is based on the JPL solar system ephemerides and the StarLink 'slalib' function set. This client is probably a temporary one, which will be superseded by more elaborate functions in the AIPS++ Measures system. The immediate purposes for "solar_system" are to track the moon and planets with the GBT software and to provide a few functions of general utility such as precession/nutation, aberration, UTC to LST and LST to UTC conversion, doppler calculation, and pulsar pulse delay. The client events decribed in more detail below are Event Name Input Value Record object_track [object=, mjd=, utc=, num_pts=, interval=] object_doppler [object=, mjd=, utc=, num_pts=, interval=] doppler_fraction [ra=, dec=, mjd=, utc=, num_pts=, interval=] observer_position_velocity [mjd=, utc=, num_pts=, interval=] pulse_delay [ra=, dec=, mjd=, utc=, num_pts=, interval=] utc_to_tdb [mjd=, utc=] utc_to_last [mjd=, utc=] last_to_utc [mjd=, last=] j2000_to_epoch [ra=, dec=, mjd=, utc=] epoch_to_j2000 [ra=, dec=, mjd=, utc=] add_aberration [ra=, dec=, mjd=, utc=] remove_aberration [ra=, dec=, mjd=, utc=] set_observer_coord [x=, y=, z=] geocentric_observer_track [mjd=, utc=, num_pts=, interval=] barycentric_observer_track [mjd=, utc=, num_pts=, interval=] barycentric_earth_track [mjd=, utc=, num_pts=, interval=] barycentric_object_track [object=, mjd=, utc=, num_pts=, interval=] | |
