Historical Notes:
Version 15-Dec-1993 **** NOTE that there was an error in minor planet #418
Version 29-Jan-1994: rough error in the mean motion of minor planet (418)
Alemannia was found by V.Shor and corrected.
Version 04-Feb-1994: modification in minor planet (719) Albert
which was observed only in the year of its discovery 1911,
and is the only planet which is considered now to be lost.

1- 6 I6 --- N Minor Planet number
8- 11 I4 a Equinox equinox = 2000 (2000.0)
12- 15 I4 a EpY epoch (year)
16- 17 I2 month EpM epoch (month number)
18- 19 I2 d EpD epoch (day number)
In most cases epoch is written as 19920627
(month and day may contain leading zero);
it is supposed that epoch is given
for 0 E.T. even for dates before 1925
20- 29 F10.6 deg M mean anomaly
30- 39 F10.6 deg omega argument of perihelion
40- 49 F10.6 deg Node node
50- 59 F10.6 deg i inclination to the ecliptic
60- 69 F10.8 --- e eccentricity
70- 81 F12.10 deg dmotion mean daily motion
82- 87 F6.2 mag H absolute magnitude, H
89- 93 F5.2 --- G []? slope parameter, G
95-103 9I1 --- Pert nine-figure code consisting of zeros and ones;
one in i-th position of the code means
that perturbations from the i-th major
planet (counting from Mercury to Pluto)
has been taken into consideration when
determining the elements.
104-112 9I1 --- Pert2 further indications of perturbing bodies:
Ceres, Pallas, Vesta
(the remaining six bytes 107-112 are zero)
113-116 I4 --- Nopp number of oppositions used for improvement
117-120 I4 --- Nobs number of observations used for improvement
121-124 I4 a Y1 the first year of the time interval covered
by the observations used for improvement
125-128 I4 a Y2 the last year of the time interval covered
by the observations used for improvement
129-133 F5.1 --- rms mean-root-square residual or maximum
residual of observations with respect to
the set of elements fitted by least
squares. In the last case 50 is added to
the absolute value of the residual
134-139 A6 --- code code for the source of elements consisting of
one or two letters and four or five digits;
the letters MP and four digits or M and
five digits stand for the Minor Planet
Circular and the page; the letters EP and
four digits stand for the Ephemerides of
Minor Planets and the year.
140-155 A16 --- Name name or preliminary designation of the planet
164-181 A18 --- Author author of the elements
182-187 A6 "YYMMDD" Date six-figure code of the date when the elements
have been written on tape at ITA (two last
figures of the year, month, day)
