short int local_star (double tjd, short int earth, double deltat,
fk5_entry *star, site_info *location,
double *ra, double *dec)
Computes the local place of a star, given its mean place, proper
motion, parallax, and radial velocity for J2000.0, and the
location of the observer.
tjd (double)
TDT Julian date for local place.
earth (short int)
Body identification number for the Earth.
deltat (double)
Difference TDT-UT1 at 'tjd', in seconds.
*star (struct fk5_entry)
Pointer to catalog entry structure (defined in novas.h).
*location (struct site_info)
Pointer to structure containing observer's location (defined
in novas.h).
*ra (double)
Local right ascension in hours, referred to mean equator and
equinox of J2000.
*dec (double)
Local declination in degrees, referred to mean equator and
equinox of J2000.
(short int)
0...Everything OK.
>0...Error code from function 'solarsystem'.
See the discussion for function topo_star. Function local_star is identical to topo_star in input
arguments and use. The local place is essentially the topocentric place expressed in the coordinate system
of standard epoch J2000.0.
