Scheduling rules:

Current implementation in geopipeline:
- computed for Malargue (ESTRACK)
- visibility events start when ground-station to SC reaches 10 deg elevation above local ground station horizon
- 8 hours (9 hours with slew) segment defined from the visibility start
- slew times of 30mn added TWICE to simulate slew toward the HGA pointing (assumed to start slewing at visibility start event) and back - so the total pass duration is 9h as default
- Filtering for the TOUR phase: remove those segments where at least one occultation is found by (jupiter, callisto, europa, ganymede or io) AND/OR if part of segment in superior solar conjunction (SES limit 3 deg)
- Filtering for the Ganymede phase: segments redefined around occulting bodies (jupiter, callisto, europa, ganymede or io), keeping only segments with at least 3h10 mn duration to take into account 5 mn margin before and after each occultation AND/OR superior solar conjunction taken into account (SES limit 3 deg)
- Both filtered and unfiltered passes files are produced, for each station

Contextual Parameters:

Comments:

during first 8 hours of visibility of MLG station. Extended during phase 3.
