* Select Output coordinate system:

* Select resolution: Hourly Daily (equal hourly values for hour=0 )


* Select Data precision: (decimal places for AU)

* Select Time Span: Start year: Start day: Stop year: Stop day:


Optional: Name of additional S/C or object 2*:
*In this case the difference of between coordinates of the sun and first object and the sun and second object,
and Distance between two selected objects will be calculated
Output data will be calculated for Equinox Epoch: "Mean of date"
