Major Instrument Modes: UVES Red_520

RA Range: 4.5h

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 0.6, CLR, 2.0, 1.0, 30


Pre-imaging run? No! Chilean run? No! Special calibrations? No!
Time critical? Yes! ToO? No! Carry-over run? Yes!


Special Remarks:
New Targets and Ephemeries provided in separate file (267.C-5701A.001.eph)


 
 
  Carry-Over program (from last semester when 1 OB only was executed) aimed 
at observing Titan with the slit along the equator, rotated by 180 between 
two consecutive observations. Should problems arise during positioning of 
the slit on target, check README file for suggested procedure. Since very 
accurate velocities need to be measured, user has included two wavelength 
calibrations per OB.

 Important requirements: seeing below 0.6" (this corresponds to 3/4 of 
the apparent diameter of Titan), and 10 daytime FF (instead of the regular 
5). Target observable within airmass constraint starting late August. 

 Coordinates given in the OB are only approximate: correct values of
position for each day are given in the updated table 267.C-5701A.001.eph,
together with proper motions in arcsec/sec. These will have to be updated 
and or typed in every time a new OB is executed. Proper motions can be 
used if PSO prefers to use the ACQ option ADDVEL.

 NEW (09.01.03): exposure time of last OB for Titan was reduced in order to 
include 2 new short OBs on Saturn and Io (ephemeries for these 2 objects are 
also listed in the same file as for Titan). Change was approved by USG.
