RA/decs are astrometric J2000 coordinates (corrected for light
time lag, but in the inertial J2000 frame, i.e., not rotated
for precession or nutation, and differential light deflection is
not included.) Display can be turned on/off in the 'advanced
options' for ephemerides. When turning them on, you can select
from various format choices (base-60, decimal, different
precisions, etc.)
Distances are in kilometers for distances under one million km
(about 0.00668 AU), and in AUs for larger distances.
The "SM" (Sun-Moon) flags consist of one or two letters, extended
from a scheme used on JPL's Horizons system. Letters used are :
* Daytime (sun above horizon)
C Civil twilight (sun below horizon, but by less than 6 degrees)
N Nautical twilight (-12 < sun's altitude < -6 degrees)
A Astronomical twilight (-18 < sun's altitude < -12 degrees)
m Moon is in the sky, less than 50% illuminated
M Moon is in the sky, more than 50% illuminated
l Object transiting in front of moon
L Object occulted by moon
a Below altitude/horizon limits set for the observing site
d Outside declination limits for your site/mount
e Outside elongation limits for your site/mount
h Outside hour angle limits for your site/mount
g Some galactic confusion
G Lots of galactic confusion
B Object is below the horizon
Uncertainties are one-sigma values shown in arcseconds (unless they
are very large, in which case they are shown in arcminutes or degrees).
In theory, the object should be within this distance of the nominal
RA/dec 67% of the time, within twice that distance 95% of the time,
and within three times that distance 99.7% of the time. In practice,
astrometric errors are not actually Gaussian, which means these
uncertainties are sometimes over- or underestimated. So you may have
to look farther, or not nearly as far, as the uncertainties say.
The object will probably be offset from nominal somewhere along the
indicated position angle, especially if the orbit is well determined.
Three-letter constellation abbreviations specify the constellation
containing that RA/dec, as defined by the IAU's 1930 delineation.
