Date - date of observation. 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. Obs - observatory code (see below). 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 ), 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 result Q=2 - result following from low quality photometry. Smin - minimum of the normalized modelled flux. Results obtained in the cases where only position angle could be determined (total mutual eclipse or occultation observed).

Date - date of observation. 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. Obs - observatory code. 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. R - sign showing the reason why only one coordinate was determined: 0 - for a total mutual eclipse or occultation observed, 1 - for the results obtained from poor 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.
