Notes

OXD means "Orbit Crossing Distance". OXT means "Orbit Crossing Timing". CAD means "Close Approach Distance".

Data for active spacecraft and natural bodies are displayed in the tables above. Data for inactive spacecraft are not displayed, but they are available in the conjunction metric tables and plots, which have been stored in the output directory listed below. Data for reference trajectories are not considered for Red events, but are considered in the All section for events not covered by the predicts file. Reference trajectories use the same thresholds as the nominal trajectories.

The note after the probability value listed for RED events refers to the source of covariance data used for the probability calculation, with the following definitions:

C - Covariance data provided by the mission in OEM format.
P - A covariance converted from the RED threshold polynomial coefficients listed below.
N - No covariance data, worst case covariance assumed for this body.
No Data - Probability could not be calculated due to a lack of covariance data from both bodies.

For more information, please see the point of contact listed below.

Red OX Distance Threshold = OXD0 + (OXD1 * t) + (OXD2 * t^2) [km]
Red OX Timing Threshold = OXT0 + (OXT1 * t) + (OXT2 * t^2) [sec]
where t = CA Epoch - Ephemeris File Submit Time (in days)

Red thresholds are based on 3-sigma values. Thresholds listed as "P" are based on a quadratic fit of the 3-sigma values as a function of time to the event. The polynomial coefficients used are listed in the table above. Lines for coefficients which have been updated since the last run are colored blue, and each line's body is marked with an "*". Thresholds listed as "C" are based on 3-sigma covariance data provided by the mission.

All Thresholds -- Constants

Body	Name	OXD (km)	CAD (km)
1	Odyssey	10.00	100.00
2	Mars_Express	10.00	100.00
3	MRO	10.00	300.00
4	TGO	10.00	100.00
5	EMM	10.00	100.00
6	Tianwen1	10.00	100.00
7	Phobos	45.00	100.00
8	Deimos	60.00	200.00

All OX Distance Threshold = OXD
All CA Distance Threshold = CAD

All thresholds are always constants. The constants used are listed in the table above. Lines for constants which have been updated since the last run are colored blue, and each line's body is marked with an "*".
