Comments.
From reference.
We give astrometric results derived from reduction of 65 lightcurves made in
1995-1996 during the PHESAT95 campaign (Thuillot et al. 2001) and 4 results
derived from Japanese observations made in 1980 (Soma & Nakamura 1982). The
accuracy of these results is about 20-30 mas.
The format of the present results are very near to the one of (Strugnell &
Taylor 1990), more precisely it is the same as (Vienne, Thuillot, Veiga et al.
2001).
There are three kinds of results: the best ones (reference 420), other good
ones (reference 421) and the other ones, with a reference xxx, because we advise
against using them. The split into these three groups has been made when
visually comparing the measures with the adjusted theoretical lightcurves, and
not when using the residuals.
Format.
1. Opposition number, 1=1874 to 118=1995.
2. Year of the moment of observation.
3. Month of the moment of observation.
4. Day of the moment of observation with decimals.
5. TT-UTC in seconds.
6. UAI observatory code from the Minor Planet Center.
7. Qualification of observations (420 - the best ones,
421 - other good ones, xxx - other ones, because we advise
against using them).
8. Observation type ( 1 - X, Y)
9. Subject satellite (Ns), reference satellite (Nr), Ns*10+Nr.
10. 11 (flags of presence of the first and second coordinates)
11. Value of X, arcsec.
12. Value of X, arcsec.
13. Reference system (2 - mean equator and equinox of J2000).
14. Reference frame (1 - geocentric, 2 - heliocentric).
15. Residuals of observations in X, arc-seconds (computed with TASS1.7)
16. Residuals of observations in Y, arc-seconds (computed with TASS1.7)
17. The number of the satellite used as reference in the computation of residuals.
