Estimated Total Execution Time (hours, including overheads)

• 6 hours

General Description

• Titan is observed during the Cassini flybys. The combination of ground-based
   spectro-imaging data in conjunction with Cassini/VIMS spectro-imaging data at different
   phase angles are essential for determining the scattering properties of Titan's
   haze layers and serve as input for atmospheric models.
  
  The OB names contain the dates of the nights when they should be executed. See time-critical
   aspects!
  
  AO acquistion: The AO loop is closed on Titan itself.
  
  For all OBs (titan_*):

Time-Critical Aspects

• The OBs are named with the dates of the nights where they should be executed.
   (The dates refer to when the night is starting.)
  
  The table below lists the ideal times to execute the OBs (higest airmas ~1.3). In
   praxis, it would be helpful to stay within an hour of this time to keep the airmasses
   comparable. For the flyby T22 only one observations is planned. For the flybys T23
   through T27, we intend to observe also the night before and the night after the
   flyby (hence 3 OBs are provide per flyby). Three spare OBs are provided.
