The values "O-C" are preliminary and must be revised
Format.
1. Acceptance code: 1 Accepted data, 0 - Deleted (bad quality)
2. Opposition number: 1 - 1877, ..., 50 - 1982
3. Year of the moment of observation
4. Month of the moment of observation
5. Day of the moment of observation with decimals
6. (ET-UTC) in tenths of second
7. Observer code
8. Observatory N
9. Observed body: 1 - Phobos relative to Mars
2 - Deimos relative to Mars
3 - Deimos relative to Phobos
10. Obs. type: 0 - separation and/or position angle
1 - differential R.A.(*cosine(dec.))
and/or differential declination
2 - Delta alpha or Delta delta
11. Presence flag for 1st value of pair:
0 - value absent
1 - value present
12. Presence flag for 2st value of pair:
0 - value absent
1 - value present
13. Ref. system: 1 - true equator and equinox of date
2 - mean equator and equinox of B1900
3 - mean equator and equinox of B1950
4 - mean equator and equinox of J2000
14. 1st value of observation, seconds of arc (0.0 if absent), see note 4
15. 2st value of observation, seconds of arc or degrees if position angle
(0.0 if absent), see note 4
16. 1-sigma noise in 1st value of pair (seconds of arc)
(0.0 if absent), see notes 3, 4
17. 1-sigma noise in 2nd value of pair (seconds of arc)
(0.0 if absent), see notes 3, 4
18. Observation correction (reduction) code:
0 - not corrected or no information
1 - corrected for phase,
2 - corrected for differential refraction
3 - both 1 and 2
Notes:
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.
