EnVision Science Orbit Events
================================

VERSION:        2.0
CREATION_DATE:  2019/07/26 
ORIGINATOR:     ESA/ESOC (P. Munoz)


CONTENT: Event file (G/S visibilities, occultations, eclipses) in XML format covering the Science Orbit duration for two different scenarios:
  
  - ESC_T2_2032_SouthVOI: launch into direct escape at -3.0 deg declination and Venus Orbit Insertion over the Southern hemisphere.
  
  - HEO_T2_2032_NorthVOI: launch into HEO (310x100,000 km) and Venus Orbit Insertion over the Northern hemisphere.


NOTES:

  - G/S visibilities are provided for elevation cut-off angles of 10 and 20 degrees.
  
  - Eclipses and occultations are computed very conservatively for a Venus radius augmented by 200 km to take into account the atmosphere.
    For reference, if smaller radius extensions of 100 or 50 km were used then the event durations would be reduced by approx. 2 or 3 min resp.
