Colums                       Entry
1		Acceptance code - A = Accepted data
                                - D = Deleted (bad quality) data

3-4		Opposition number - 1877 = 1, 1982 = 50

6-19		Observation time (UTC), Not light-time corrected,
		with the form YYYYMMDD.DDDDD

21-23		(ET-UTC) in tenths of second

25-26		Observer code: Kiseleva = 32

28-30		Observatory code: Abastuman = 119
 
32		Observed body - 1 = Phobos relative to Mars
			      - 2 = Deimos relative to Mars
			      - 3 = Deimos relative to Phobos

34		Obs. type     - 0 = separation and/or position angle
			      - 1 = differential R.A.(*cosine(dec.))
				    and/or differential declination
			      - 2 = Delta a or Delta d

36		Ref. system   - 1 = true equator and equinox of date
			      - 2 = mean equator and equinox of B1900
			      - 3 = mean equator and equinox of B1950
                            
39-45		1st observation of pair (seconds of arc)
			      - blank if observation absent
			      - see note 4.

48-54		2nd observation of pair (seconds of arc or degrees if position
		angle)
			      - blank if observation absent
			      - see notes 1 and 4.

58-61		1-sigma noise in 1st obs. of pair (seconds of arc)
			      - blank if observation absent
			      - see notes 3 and 4.

64-67		1-sigma noise in 2nd obs. of pair (seconds of arc)
			      - blank if observation absent
			      - see notes 2, 3 and 4.

70		Observation correction code
			      - 1 = corrected for phase
			      - 2 = corrected for differential refraction
			      - 3 = both 1 and 2	

Note 1.		The units for the observations are seconds of arc except for 
		position angle when the unit is degrees east of north in the
		range 0 - 360.

Note 2.		The units for the observation noise are always seconds of arc.
		For a position angle p, the noise refers to the product of the
		error in p and the separation angle.		
	
Note 3.		In the ESOC system, when the noise is greater or equal to 99.0
		the corresponding observation is of bad quality and is not used
		in the determination of the orbit but its residual is computed
		and printed.

Note 4.		When the observation is either Delta a or Delta d the columns 
		normally used for the complementary observation are used to
		store the position angle, theta. Also, the columns normally 
		used to store the noise of thre complementary observation 
		contain 0.0.
