Astrometric results of observations of mutual occultations and eclipses
of the Galilean satellites of Jupiter in 2014-2015.
Explanations.
Version 2017.01.27
 
Explanations to the Table of astrometric results (first type).
 

Obs - observatory code (see below).
Type - the type of the phenomenon (eclipse or occultation)
     including the satellite numbers in the form "nem" or "nom",
     where n is the number of the occulting or eclipsing satellite
and m - is the number of the occulted or eclipsed satellite.
Date - date of observation.
UTC - the time instant in the UTC scale (h, m, s).
X, Y - X=Delta(alpha)*cos(delta), Y=Delta(delta)
     (occulting satellite relative to occulted one
     or eclipsing satellite relative to eclipsed one)
     in arcseconds in ICRF.
sigmaX, sigmaY - rms of X, Y, correspondingly, in arcseconds.
     This is because of random errors of the photometry.
O-C_X, O-C_Y - differences of X, Y from the results
     of the satellites motion theory ( V. Lainey V2.0 ), in arcseconds.
s, pos - apparent distance (arcsec) and positional angle (deg.),
     accorsding to X, Y .
Q - index of the result quality, following from processing:
     Q=0 - normal result,
     Q=1 - doubtful photometric data
Smin - minimum of the normalized modelled flux.
 
Explanations to the Table of astrometric results (second type).
 
Obs - observatory code (see below).
Type - the type of the phenomenon (eclipse or occultation)
     including the satellite numbers in the form "nem" or "nom",
     where n is the number of the occulting or eclipsing satellite
and m - is the number of the occulted or eclipsed satellite.
Date - date of observation.
UTC - the time instant in the UTC scale (h, m, s).
pos - position angle (degrees, ICRF) of the occulting or eclipsing satellite
     relative to the occulted or eclipsed one.
prec. - precision (arcsec) of apparent position
     along the apparent relative trajectory of the satellite
     as obtained with the least-square method.
O-C_L - differences of the apparent relative satellite position
     along the satellite track from the results
     of the satellites motion theory ( V. Lainey V2.0 ), in arcseconds.
Q - sign showing the reason why only one coordinate was determined:
     Q=0 - normal result,
     Q=1 - doubtful photometric data
In these cases the apparent relative position of the satellite
measured across the apparent trajectory can not be determined
accurately enough and therefore position angles can be determined only
up to ± 180 degrees.
