Notes:
 C/A: geocentric closest approach, in arcsec
 P/A: Planet position angle wrt to star at C/A, in deg
 vel: velocity in plane of sky, in km/sec, positive= prograde, negative= retrograde
 R: instrumental magnitude in UCAC2 system
 J, H, K: 2MASS magnitudes (50.0 = not in 2MASS)
 R*, J*, H*, K* are normalized magnitudes to a common
 shadown velocity of 20 km/sec by the relationship:
 Mag* = Mag_actual + 2.5*log10[velocity/20 (km/sec)]
 Delta: Planet range to Earth, AU
 long: East longitude of sub-planet point, deg, positive towards East
 loc. t.= UT + long: local solar time at sub-planet point, hh:mm

 Selection criteria:
 Maximum geocentrique closest approach considered:  0.33500000000000002       arcsec
 Day light exclusion (range loc. t.): 12.0hs to 12.0 hs (t1 = t2 -> no exclusions)
 List below has:            3  entries
 Reference ephemeris: DE418/JPL_13                                      
 Offset applied to ephemeris off_ra(mas) = A * (t-t0) + B 
 Offset applied to ephemeris off_de(mas) = C * (t-t0) + D 
 t0 =    2005.0000000000000       yrs
 A =    0.0000000000000000       (mas/yr)
 B =   -87.000000000000000       (mas)
 C =    0.0000000000000000       (mas/yr)
 D =    1.0000000000000000       (mas)
 pm = proper motion applied? (ok, no)
 ct = uc (UCAC2); 2m (2MASS); fs (field star)
 f = multiplicity flag
 0 - no multiple entries per star in astrometry
 1 - single position from 2 or more uc/2m entries
 2 - single position from 1 uc/2m entry only
 3 - fs position from entry with more N contributions
 4 - fs position from entry with best (x,y) error
 5 - fs position from entry with brightest R mag.
 6 - fs position from average over all entries
 (see details in Assafin et al. 2009)
 E_ra, E_de: error of star position (mas); (9999 = no estimation)
 pmra, pmde: star proper motion (mas); (9999 = no proper motion)
